Your Knife, My Heart by K.M. Moronova is a brutal, addictive dark romance where violence, obsession, and connection collide.

Cameron Mortem is a weapon with a fatal flaw. Brilliantly lethal and officially unstable, he has a habit of killing the people assigned to fight beside him. An experimental drug fractures what little control he has left, and the Dark Forces respond the only way they know how. By throwing him back into the Under Trials. His single rule is simple. Do not kill the new girl.

Emery Maves should already be dead. Instead, she is forced into the same merciless system, paired with a man everyone else fears. Survival means learning Cameron’s patterns, his limits, and the truth beneath his reputation. What she finds is far more dangerous than madness. It is restraint. Devotion. A tenderness that should not exist in a world built on blood.

As the Trials strip them both to the bone, desire and destruction begin to blur. Loving Cameron could cost Emery her life. Losing her could destroy what remains of him.
