Summer Coffee by C.S. McKinney

The scars that lingered from betrayal felt unbearable, that was until Nate met Ellie, who was still living in her own nightmare. When a misplaced wallet at the coffee shop lands in Ellie's hands, Nate finds a new light in his life. Upon falling for the girl whose dark secret falsely portrays her age, his sole purpose becomes protecting her, even if it means losing everything.
