One Salty Beach by Elisa Leigh

Brody Wilkes knows who he wants to spend his life with, only she won’t give him the time of day, until one night something changes. Tired of all the back and forth between them, he sets out to prove to her why they’d be perfect together.
Winona “Winnie” Graves is in love with her best friend’s brother. She knows it’s wrong and tries to avoid him at all costs, but one night she lets down her guard and gives in.
Will Brody and Winnie get the happily ever after they both want so badly? Or will Winnie’s friendship with Ella prove to be more important?
