SPoLaFS has some really great marketing--the cover, the plot summary, all of that. I was thinking this would be a Before Sunrise, but on an airplane. Because, you know, Before Sunrise is amazing. Unfortunately, fairly or unfairly, those expectations weren't met for me. And, to frustrate me further, there is a very sizable storyline about Hadley, the main character, and her father (a straight up cheater, who ran off with a woman he met while serving as a visiting instructor in England) that did not sit well with me and was far too tidily wrapped up. 
 The first 50 percent or so of SPoLaFS was delightful, really. I loved the main character's good humor, the dynamics between she and Oliver--it was all very charming (yay!). So much so, that I would have loved the entire novel to be about the flight. For, for that portion of our journey, I'd give the book a solid 4 stars. 
 However, the second half takes place in England, and it deals with Big Family Issues. Now, I have no problems with novels about Big Family Issues (ie, I just 5-starred Bittersweet, which is very much about Big Family Issues), but the resolution to these Big Family Issues takes place in a very abbreviated timeframe and I had a very hard time believing that they should have been resolved at all. This book falls into a common trap in YA lit, in which the young person is expected to forgive the Parent Who Did a Bad Thing, even when they're not deserving of it. (view spoiler)[Apparently, all can be resolved by a father-daughter dance these days. (hide spoiler)]The more I've thought about this in the days since I finished the novel, the more this (fairly sizable) portion of the novel bother me. This section of the book would get maybe 2-ish stars from me. 
 I do think that its intended audience (teens, especially those on the younger side of things) will gobble this book up and enjoy it to pieces. 
 I have mixed feelings on this one... got to chew on it for awhile. A well written novel, loved the scenes between Oliver and Hadley, but I had a very visceral reaction to the storyline with Hadley's father, and its resolution.
