Pulse Zero

Pulse Zero is giving toxic supervillain obsession with a kidnapped boy, years of unfinished tension, and the kind of “this is terrible but I’m seated” chaos dark MM readers live for. Cason and Reese are messy, dangerous, and wired together in that obsessive enemies-to-lovers way where closure is absolutely not the point — possession is. You’re getting kidnapping, blood, gore, torture, breath play, fear play, and a whole lot of power imbalance, so go in with eyes open and triggers checked. But if y’all want dark, twisted, supervillain-level devotion with a hard-fought HEA? This one is going straight on the one-click shelf.

Book Description

There are moments when everything stops.

A breath. A heartbeat.

Even when it feels like an ending, it isn’t. It’s not a beginning either. It’s something narrower, a precise point in time. It’s a transition, a reconfiguration. The space between one pulse and the next. The point where one part of your life collapses inward and converges with the one to come.

That’s what happens to me the day I’m taken. Turns out, being Cason Bellrose comes with consequences no one bothered to mention.

But then the man who stole me is ripped away. Reese Morgan. His name still tastes like something unfinished.

Years later, I’m still chasing truth, closure, tearing through shadows that don’t want to be found. Whatever will help me move on. And the deeper I go, the more I become tangled in things I don’t understand.

Life changes people. But so does death.

If there’s something waiting for me in the dark, I’ll find it. Even if it means stepping into that space between one pulse and the next.

And not coming back the same.

Pulse Zero is a dark MM romance with toxic, obsessive supervillains and a hard-fought HEA. It’s a spin-off of the Echoes duet but can be read as a standalone. Specific content warnings can be found on the author’s website.

Content Warnings

This one comes with a heavy dark-romance trigger load: kidnapping/abduction, captivity, murder, assault, blood and gore, on-page near-death experiences, grief and trauma, PTSD, Stockholm syndrome, torture and violence between MCs, and a major power imbalance. Sexual content includes choking, breath play, fear play, pain play, dub-con, and consensual non-consent/CNC. The author also notes past death of a parent, not on-page. Definitely a “check the warnings first, then buckle up” read.

READ MORE
Here is something most of us learned the hard way. A dark romance can be a four-star read on the page and a five-star read in your ears, or the exact reverse. The book never changed. The voice did. That gap is wider in this genre than almost anywhere else in fiction. And right now the entire audiobook industry is arguing about who — or what — should be doing that voice work. So let's talk about it. ## Why Voice Matters More in Dark Romance Most genres treat audio as a simple delivery system. You are driving to work or folding laundry, and the story goes in through your ears instead of your eyes. That is fine, and it is why audiobooks exist. Dark romance does not work that way. **In this genre, the voice is part of the threat.** Think about what our books actually run on. A man says something calm and completely terrifying. A heroine says no and means it, or says no and does not mean it, and the entire scene turns on which one it is. A stalker hero narrates a conversation the heroine has no idea he is overhearing. None of that is plot, and all of it is tone. On the page, you supply that tone yourself, using whatever your imagination hands you. In audio, a stranger supplies it for you. When that stranger is the right performer, the book becomes noticeably sharper. When they are wrong for the book, a scene that should feel genuinely dangerous ends up sounding like a man reading a grocery list in a low register. That is the whole argument in one sentence. **A narrator is not reading your dark romance to you — they are performing a second lead character.** ## Single, Dual, Duet: Know What You Are Buying Plenty of readers use these three words as though they mean the same thing. They do not, and the difference changes the whole listen. **Single narration** means a single performer voicing every character in the book. That is fine for single-POV stories, but it gets risky in dual-POV dark romance. One performer has to make both leads sound like separate people. **Dual narration** means two narrators who split the book by chapter. He reads his chapters and she reads hers, and each of them still voices the other character inside their own chapters. **Duet narration** means both narrators are in the same scene. He speaks his lines, she speaks hers, and the two recordings are edited together afterward. Lovely Audiobooks has a clear breakdown if you want the technical version. I will take a side here. **For dual-POV dark romance, duet is the superior format, and it is not remotely close.** Here is my reasoning. Our genre lives on power imbalances inside a conversation — who interrupts, who goes quiet, and who lets a threat hang there for two extra seconds. Duet lets two separate performers play that dynamic against each other. Dual narration asks one person to act out both halves of a fight, which is a genuinely difficult thing to pull off. ACX, Audible's production arm, has been openly promoting dual and duet as a romance format for several years now, which tells you the reader demand is real and not just a wish. The counter-argument is fair, though. Duet productions cost considerably more to make, so far fewer indie dark romances ever get one, and plenty of excellent books are single-narrated for budget reasons alone. Skipping every non-duet title would cut out half the genre. Treat duet as a bonus, not a rule. ## The AI Narration Fight Now for the loud part. In May 2025, Audible announced it was rolling out AI narration for publishers, offering more than a hundred synthetic voices across English, Spanish, French and Italian. The company also began testing AI translation, including a speech-to-speech version that preserves the original narrator's voice while switching the language underneath it. The rules are still messy. As of 2026, the standard ACX upload path still asks for human narration, while Amazon's separate Virtual Voice program is where most AI-narrated titles live. Other retailers generally require authors to disclose AI narration at upload. So AI audio clearly exists, but it is not labeled the same way everywhere yet, and that last point is worth watching rather than treating as settled. Readers, meanwhile, have already voted. The 2026 Written Word Media reader survey found that **more than 80% of readers prefer human narrators, while under 1% strongly prefer AI voices.** I think those readers are correct, and not for sentimental reasons. Dark romance depends on the tiny details: a breath before a line, or a word delivered flat when it should have landed warm. Those choices are interpretation, not pronunciation. A synthetic voice can pronounce every word correctly and still completely miss what those words are doing underneath. There is a real counterpoint here. AI narration means smaller authors can finally afford audio at all, and a backlist that would never earn out a human narrator can reach listeners in a week. For readers with vision issues or reading disabilities, more audio is a genuine accessibility win, and that matters considerably more than my personal taste does. My honest position: **AI narration works as a floor and fails as a ceiling.** Use it to make a book exist in audio. Do not use it on the book you want people to fall in love with. ## Where People Are Actually Listening That same survey found only about **22% of readers listen to audiobooks at all**, which is dramatically lower than BookTok makes it feel. Among the readers who do listen, **51% borrow through Libby or Hoopla, and 48% use an Audible subscription.** That library number deserves far more attention than it currently receives. If you have been rationing monthly credits, your local library app is probably sitting on a substantial chunk of the dark romance you want, completely free. Indie titles are still thinner there than traditionally published ones, but the gap has narrowed considerably. ## The Public Listening Problem We should also be honest about the other complication. Dark romance in audio hits different in public. The page is private. Audio is one loose earbud away from a coworker overhearing a scene you cannot possibly explain. Add duet narration and full sound design, and it stops being a book and becomes a radio drama about a knife. Most of us solve this the same way. Spicy scenes get saved for the car or the house, while plot and setup get the gym and the commute. It is a slightly ridiculous system, and it works beautifully. ## How to Vet a Narrator in Two Minutes Before you spend a credit, run through this. 1. **Play the sample all the way through**, not just the first ten seconds, because bad matches usually reveal themselves around the forty-second mark. 2. **Check what else that narrator has recorded**, since a narrator who mostly performs sweet contemporary may not have the register for a cartel book. 3. **Search the narrator's name alongside the book title**, because reader reactions to narration are loud and easy to locate. 4. **Look for the format label**, as "duet" or "dual" is normally listed in the audiobook details on the retailer page. If it is missing, assume single narration. 5. **Check for an AI or Virtual Voice tag**, which is not a dealbreaker for everyone, but you should know before you buy. If you want current titles to test this on, Book Riot's 2026 dark romance roundup is a decent starting shelf. *Harvest Season* by Brynne Weaver and *Midnight Message* by Avina St. Graves both show up on it. *Twisted Pawn* by L.J. Shen is out in audio right now, and Harley Laroux's *Losers: Part One* has been rereleased with a deluxe edition, which has the audio conversation around it running hot again. > Hunting a flavor — stalker, captor, monster, mafia — rather than one book in particular? You can filter by trope and by content warning on Dark Romance Reads and skip the scrolling. > ## So Where Does That Leave Us Audio is not a lesser version of reading. In dark romance it can genuinely be the superior one, because so much of what we come for is carried inside a voice. That is exactly why the AI question is not a minor technical one. If the voice is doing half the work of the book, then who is doing the voice becomes a real question about the book itself, not a production footnote. Pick your narrators the way you pick your morally gray heroes. Carefully, and with a full sample. Disagree with me? Tell me which single-narrated dark romance beat every duet you have ever heard. I will go listen to it. --- Tired of blurbs that lie to you? Dark Romance Reads lets you search by trope first — mafia, captor, bully, monster, and everything darker — and filter out whatever you'd rather skip. No more one-clicking a book only to find out it wasn't your thing forty pages in. Browse the library, or get it delivered weekly straight to your inbox. **Find Your Next Read**
