The sirens have been hunted for so long that we no longer remember our pasts... Our songs have been stolen, the source of all our power, and it's been made punishable by death to use it. They've taken everything from us. The vampires. I've been sent to the darkest of all places, Nightmare Penitentiary for my next assignment. But I've promised myself this assignment will be my last... no matter the cost. I'll do whatever it takes to free my people, even if I end up shattering the hearts of three captivating men who have the power to change my future forever. One will sacrifice himself for me. One will shatter my soul. And one will kill me to save me. Welcome to Nightmare Penitentiary. Escape is my only option.

What is a siren without her power? I'm about to find out, and I have no problems embracing the darkness to do so. I was thrown into a literal hell, and every day feels like it could be my last. But amid such darkness, I thought I found light with three men who've shown me happiness is possible even in a place like this. Except, maybe I was too quick to trust and give my heart away. They say trust takes years to build, seconds to break... and I don't think forever will be long enough to repair what they did to me. One will sacrifice himself for me. One will shatter my soul.And one will kill me to save me. Enjoy your stay at Nightmare Penitentiary. Death is only a matter of time.

What happens to a siren who's come back from the dead? I hope I get the chance to find out. I've been betrayed, destroyed by the three men that I'd given my trust. I’m alone again in this place… a place that’s darker than hell. And worse, something strange is happening to me. Something that has me wondering if I can even trust myself. There are so many secrets in these walls, and I’m now determined to find them all out. I’m done playing nice. This siren’s going to sing once again. Nightmare Penitentiary doesn’t know what’s coming. One will risk the safety of our future. One will reveal a heartbreaking betrayal. One will bring out my own demons. And one might just be the savior I’ve been looking for. Don’t outstay your time at Nightmare Penitentiary. Some places you just don’t survive.

One man broke me. One led me to sin. And one killed me to save me. I grew up under the iron fist of a vampire. And when I betrayed him, I ended up in Nightmare Penitentiary. Multiple attacks, my death, and four psycho men later…I’m done being everyone's target. I have to escape the monsters who surround me within these walls. So a deal has been struck, and failure to fulfill my part of the bargain is not an option. With my fae prince, incubus, hellhound, and serial killer, I’m set to unleash hell on all of who’ve done me wrong. I’ve had enough of the cages that surround me. Sometimes all you need is a second chance to make things right. But in my case, I was given four… The final book in the Thief of Hearts series...
