Once you enter Wellard Asylum, the monsters will never let you leave.
Welcome to the bowels of Wellard Asylum, where desire is dangerous and deadly, and madness has a face. Two, in fact.
Twins Wren and Bash Norwood are serial killers, monsters in the eyes of the world. But to Dr. Caterina Vaughan, they are something far more treacherous, something intense and fascinating that she can't seem to keep her professional distance from.
As their therapy sessions blur into manipulative mind games and fantasy twists into fixation, Caterina is seduced into an unhinged web of fractured truths and buried violence. The deeper she delves into their psyches, the harder it becomes to tell whether she's curing them or they're awakening something darker that lies deep within her.
One whispers in riddles and chaos. The other paints her with words dipped in blood, using his mind to wrap her in his sinister games. Both are broken. Both are always watching, always waiting for an opportunity to sate their hunger. Both see something in Caterina that no one else ever has.
Now, neither intends to let her go, at least not alive.
They say love is a kind of madness, but in Wellard Asylum, it might just be the deadliest sin, and there's no way to escape your fate.
Darkly erotic, psychologically intense, and soaked in deadly secrets, Lethal is a razor-edged standalone thriller that asks: what happens when the one studying monsters begins to fall for them? This is book 3 of the Wellard Asylum shared world and features an MFM love triangle.
