Your Knife, My Heart
From USA Today Bestselling author KM Moronova comes a brand-new compelling and addictive dark romance in her Dark Forces world. Dark. Deadly.
Irresistible. Cameron Mortem has a problem--he can't stop killing his partners. Officially labeled clinically insane, he's also one of the most lethal assets in the Dark Forces, a brutal underground military operation built on obedience, survival, and silence.
But an experimental drug has fractured his control, making him a liability whenever someone else is on the field. As punishment, he's thrown back into the Under Trials--a merciless boot camp designed to break the weak and sharpen the ruthless. His one directive?
Don't kill the new girl. Emery Maves narrowly escapes a death sentence after her own brutal crimes, only to find herself forced into the same violent world. Assigned to Cameron, she's expected to survive the Trials and her partner's unstable nature.
But Emery quickly realizes there's more to Cameron than bloodlust and body counts. Beneath the madness lies a terrifying allure--and a strange, dangerous tenderness. As the Trials push them to their limits, Emery must navigate the brutal demands of the Dark Forces while resisting the pull of a man who could just as easily kill her as protect her.
And Cameron must fight the one urge he's never been able to overcome. Their bond is intoxicating, chaotic, and born of violence. And if it doesn't destroy them both, it might just save them.
Praise for KM Moronova's previous Dark Forces novel, Leave Me Behind: "Brutal, emotional, and unforgettable--KM Moronova pulls no punches." "A dark, aching romance that left me breathless and begging for more." "Every chapter was a punch to the gut--in the best way." "Raw, haunting, and utterly unique. I still can't stop thinking about it." "KM Moronova delivers flawed, vicious characters you can't help but fall for."

Enjoyed this book much more over the other standalone book in this dark forces universe. This ended on a cliffhanger for the second book which I will be starting immediately because that ending was seriously good. Liked the whole trials setting and the main characters!

The story was intense, I love the dynamic between the main characters but I wasn’t a massive fan of the hot and cold treatment Mori kept giving! That ending though? I need book 2 asap
