Pulse Zero by River Hale

Do not leave on your TBR, read it today


From the blurb:

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.


DuffetteReads review:

This book was wild. I haven't read the duet where Case was originally introduced but this book stands alone well enough to get thr background (and want to devour the backlist).

This was a very unique story and I'm here for every single bit of it. This story will wreck you and slowly put you back together over time.

This was my first River Hale book and this author officially made my auto one click list with this book.

Plus, Shadow Daddy. You can never go wrong with a Shadow Daddy and his Shadow Puppies.

I really hope this turns into a series because I'd love to see more from these guys, and maybe someone for Baz.

Do not let his book sit on your TBR. It deserves all the love. One of my top reads of 2026.

Pulse Zero is currently available as an e-book, hardcover and paperback and can be read as part of your Kindle Unlimited Subscription
