God of Ruin by Rina Kent

Britt's take

Landon is a prick — except when it comes to Mia. She's his one soft spot, and watching him learn sign language for her is the emotional payoff you didn't know you needed. A dark college romance between a mafia princess who won't be anyone's pawn and a tortured artist who decides she's his obsession. The story runs parallel to other books in the Legacy of Gods series, with cameos from past main characters and threads that set the next few books in motion.powe
