I expected a simple YA love story: Two teens meet on a plane, find an instant connection, and realize by the end of the flight that they're in love. 
 Well, yes, that all happens, more or less, but this book offers much more than the basic description would imply. 
 Hadley is flying to London for her father's wedding to the woman for whom he left Hadley's mother. Hadley has never met the woman, and has no interest in doing so. She's on a tight schedule, arriving the morning of the wedding, leaving the very next day. Problem? One snag after another results in Hadley missing her flight by four minutes, forcing her to take the next flight, during which she meets Oliver, heading back home to London for what Hadley assumes is also a family wedding. 
 True, they meet cute, but their connection does not feel forced or fake. They talk about nonsense, and they talk about family. They flirt, they sleep, they make each other laugh, and by the end of the flight, neither wants to say good-bye. Of course, there's more to the story than that, and while it's safe to assume that they'll meet again, the timing and circumstances are not what you'd think. 
 I really enjoyed the honest discussions about family and fears. Hadley's thoughts on her parents' separation and the impact on her role in the family felt very true to life. This may be a teen romance, but these teens have a lot on their minds and the weight of the world on their shoulders. Highly recommended.
