The Summer I Turned Pretty by Jenny Han fits the bill as an ideal summer time read. I first read this book a few years ago yet I dig it out most summers to re-read. However for Isabel (Belly) this summer is different to all the rest - she turned pretty - aka grew out of the awkward teen pubescent phase that we can all relate to (clue is in the title). No doubt every young person has experienced the tense wait for the summer holidays to begin whilst the last few weeks of school drag, this book embodies that feeling.
