Nineteen-year-old Marin Larkin has been working as a personal assistant for her famous sister Liv for the past year. Even though Marin and Liv are close, Marin has always felt like she doesn't belong in her sister's world - that she isn't good enough. When Marin's family moved to Los Angeles four years earlier, Marin naively fell in love with Connor O'Quinn, a boy who worked with Liv on both of their first movies. But soon after, Connor became a Hollywood heartthrob, and Marin's love turned to hate. Liv and Connor are now working together again for the first time in four years on a movie in Toronto, and Marin can't help but feel like she is right back to her fifteen-year-old self after years of pushing him away. The story weaves back through the years of their distant friendship and reveals what Connor must overcome to show Marin he is no longer the seventeen-year-old boy he once was. But Marin has never realized that her point of view isn't the whole truth, and she has never even considered Connor's.

Devin McKenna doesn't date golfers - end of story - but she will definitely be best friends with one. After two years of friendship (and one long year of mysterious silence) with Tate Thacker, collegiate and future-pro golf phenom, he's back for their senior year of college. Tate is the same as always; winning left and right, sticking to his insane schedule, and never being in a serious relationship. A lot had changed for Devin in that one year though. She had her heart broken by a football player, but seeing him so jealous when Tate walks back into her life makes Devin a little too happy. Fake dating might not be a thing in real life, but people used to mistakenly think that Devin and Tate were together all the time - so why can't they just not dispel the rumor for once?

Even though she's one year out of college, for once in her life, Reese Adler is going to have a summer for herself. Her little brother, who she practically raised, is finally graduating high school, so Reese has plans to spoil herself with the money she no longer has to send home - starting with seeing him walk across the stage to accept his diploma. But when a pilot strike shuts down airports across the country and Lucas Finn, the one person she absolutely hates, is proposing they road trip back home together - from Boston to Seattle - she can't believe she finds herself agreeing to get in his car. It's only one week - Luke will never change her mind about him, and the pilot strike will most likely be over by then.
