Finding Paradise by Laura Westbrook

Fun under the sun just got a lot more complicated.

Hanna’s finally going on her dream vacation after years of saving. She and her best friend, Cassie, have been carefully plotting out their trip, but it’s hard to stick to the plan when someone unexpected pops up…someone by the name of Josh.
The ocean is Josh’s life, his work, his everything. He puts his job as a scuba dive guide before everything else. Taking her by the hand, he shows her a side of island life she never knew existed.
But when her vacation draws to a close, she has to make a decision on just how serious she wants to take this newfound connection. And when his plans to go work on another island come up, the choice might happen sooner than she thinks.
