God of Malice (Legacy of Gods, 1) by Rina Kent

From USA Today bestselling author Rina Kent comes the first in a dark and steamy college romance series featuring elite criminal families and morally gray heroes. Killian Carson is unfeeling, cold-blooded, monstrous…and has developed an obsession with Glyndon that just might be both of their undoing.

Killian Carson is a predator wrapped in sophisticated charm. He's cold-blooded, manipulative, and vicious. Though his charisma and intelligence fool everyone, Glyndon sees right through him. She sees the psychopath within, and though her brain tells her to run, there's a secret part of her that knows the monster will only chase her…and she may want to get caught.

Glyndon King has never felt like anyone's favorite. Her mother and brothers are the artistic talents in the family, and she knows she will never live up to anyone's expectations. But Killian? He has no expectations except that she is now his. It doesn't matter that their schools are rivals―their possessive, all-consuming desire may be able to drown out everything else.

But can two people with broken souls truly repair the broken parts of each other's psyche? Can their dark and sinful desire overcome their history? When it turns out those pasts are more disturbingly entwined than they thought, they may come out stronger, or it may be their unraveling.
