The Playlist (Springbrook Hills #5) by Morgan Elizabeth (Romance fiction author)

"When Zoe's best friend shows her the box of dreams they put together as kids, she would never have foreseen herself dumping Mr. Perfectly Fine and quitting her draining job. But when she looks in that box and realizes her life isn't even close to where she envisioned she'd be when she was ten, she panics and implodes everything she knows. When Zander Davidson realizes his little sister's best friend is finally single at the same time he is, he knows it's time. With the help of his sister (and her dad, AKA his boss), he makes a plan to become the king of her heart, including the road trip of a lifetime, and uses the Love Story Bucket List she made as a kid as his road map. Along the way, Zee convinces Zoe to play pretend with him, but can he mastermind his way into keeping her forever and always?"
