Walmart exclusive art inside, as well as sprayed edges. I removed the Walmart sticker that was on the cover. No damage, smoke free home.

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.
