The Immortals: Book 1 of the Sizeshifters duology

by N.S. Luna

He was built to be a weapon.

When convicted criminal Cade Miller is chosen for a brutal military experiment, his sentence becomes something far worse than prison. Rebuilt, reshaped, and reborn as a weapon, Cade is no longer fully human, yet he’s expected to fight for the very system that destroyed him.

She was never meant to trust him.

Dr. Elisa Davies has spent years burying her own scars, building a life defined by control and caution. When she’s assigned as Cade’s doctor, her instincts scream to keep her distance. But the Immortal she meets is not the savage she was warned about. He’s intelligent, wounded, and more human than anyone dares to admit.

She shouldn’t crave his touch. He shouldn’t want to heal her heart. But as humanity falls into a relentless new enemy, their forbidden bond might be the one thing that saves them both.
