Born without the ability to feel pain or fear, Pennsylvania has lived his life believing he's a monster and a freak.

Because most people either keep their distance or are cruel, Penn has spent the last few years wandering from town to town, never putting down roots, never letting anyone know who he really is. Then one night he steps out of the shadows and into the light to save children from a burning house, not knowing he's saving a mob boss's kids. That split-second decision changes everything for Penn.

Gideon is a dangerous and powerful man trying to keep his territory profitable and safe, and it's been peaceful for the last couple of years. Though raising twins as a widower is hard, at least he has family to help him. Family is everything to Gideon, so when someone tries to take them away from him, the once quiet streets turn into chaos. Determined to find his family's savior, Gideon discovers so much more. His heart, which has felt like it's barely beat since his wife died, comes to life again when he looks into Penn's eyes for the first time…the man who risked everything to save his family.

With a war on the horizon, Gideon and Penn have to navigate staying alive, figuring out if there's a future for them, and destroying the real monsters trying to dismantle everything Gideon's built.
