Until His Beginning Ends by Kiki Clark 

When Death is your soulmate, finding love has never been so heart-stopping. Enzo has only had time to focus on one thing for the last few years–his thesis. He’s less than six months away from finally finishing when his whole world gets flipped upside down. By a guy dressed like a fifties greaser. Learning truths about himself and his family leaves Enzo feeling shaken, but there is just something about Theo that keeps drawing him back in. A connection between them that feels vast and infinite. Destined.
