Too Good Girl by Eleanor Lloyd-Jones

Syra Johnson was thirteen when she died inside. She was sixteen when she ran away from home and not much older when Jack Palmer saved her for the first time. Coping with her grief by shutting down, she became reckless with her life, keeping everyone at arm’s length, including Jack. Now, she’s nineteen, and her need to feel anything other than despair is as exhausting as it ever was.

Jack lives a lonely life, working at night in the streets of the seaside town where they both live. The only thing that keeps his heart beating loud enough is Syra: his friend and the girl he wishes he could love. However, his attempts to keep her from falling further get thrown back in his face, breaking him a little more each time.

Will the darkness that snatched her away drag her deeper than before, or will Syra let Jack save her again and open herself to becoming whole?
