Why Read This?The one-sentence sell. What do you get for showing up to this book, even when it's hard?

A devastatingly tender MM monster romance where a traumatized, sweet monster and a mouthy human find each other in a post-apocalyptic world. The touch-starvation trope is done perfectly, the found family feels are real, and Nyx will live in your head rent-free.

Synopsis

Ninety-one years ago, I stumbled upon a window to a strange new world. Beyond, there were blue skies and odd trees, and flowers like nothing I’d ever seen. Curiosity got the better of me, and life as I knew it changed forever. Ljómur was the military’s best kept secret. Behind those walls, I was experimented on and studied, torn apart and put back together. Caged, collared, and stripped of any sense of identity I once had. A lifelong prisoner. Now I’m free, and my former hell has been destroyed. Every bar that once confined me lies in ruin, yet I still can’t escape my cage. It’s been a month since we discovered what the military was trying to do, and since I swore to bring the group to the rifts. Ever since, I’ve been living in fear of the day they’ll call on me to fulfill that promise. No one knows better than me what’s at stake, but most days, my mind is not my own. When I’m lost inside my thoughts, only one person is able to reach me. Reyes breaks through the clouds and pulls me from that dark place in a way the others can’t. He tells me I still have something to give, but I’m not so sure that’s true. I’m just a broken thing, after all, and those can’t always be fixed. Author's note : Nyx is a First Person Dual POV MM Monster Romance series with explicit content intended for readers 18+. It is the second in a series that will have an overarching storyline carrying between books. While this series ends with a guaranteed HEA, individual books end on more of a HFN basis. The feature couple's story will be resolved, though there will be some unanswered questions and mild cliffhangers that lead into the next in the series.
