Moonlit Whisper by Amy McKinley

When Fiona’s dad asked her to tutor one of his footballers—a fourth year transfer student—she agreed. What she hadn’t expected was to come face-to-face with a ghost from her past—the boy who used to climb through her bedroom window. The one who left.
Connor moved across the pond years ago to support his mom. He hadn’t wanted to leave, not really. Now, it’s his turn and he’s back in Dublin, on the football team, and ready to make Fiona his. There’s competition both on and off the field with his former best friend, who has a piece of Fiona’s heart. Not a night goes by that he doesn’t need her in his arms. This time, he’s not going anywhere, and he won’t give up without a fight.
