The Last Piece of His Heart by Emma Scott

At Santa Cruz Central High School, they called them the misfits, the outcasts, the weirdos. But most of us knew them as the Lost Boys…
Ronan Wentz has been to hell and back, and he carries the scars to prove it. Worse, the blood of a monster runs through his veins. When his uncle gives him a roof over his head after ten years in foster care, Ronan uses this second chance to become a vigilante, walking the streets of Santa Cruz to keep the nightmares at bay. If he can use his anger to protect instead of hurt, maybe he’ll find the absolution he seeks.

Then he meets Shiloh.
Shiloh Barrera looks like she has it all together. Smart, ambitious, and full of creativity she channels into making one-of-a kind jewelry. But Shiloh’s demons drive her to succeed as much as her ambition—to prove her worth to the mother who can’t stand to look at her.

Shiloh and Ronan’s attraction is instant and scorching. Falling in love is an impossible pipe dream saved for those less damaged, but as hard as they try to resist, the feelings between them seem inevitable…until one terrible night destroys Shiloh’s dreams and Ronan’s future.
When the smoke clears and the rubble settles, they’ll have to choose: do their pasts determine their future, or can they build a new one from the broken pieces of their hearts?
