Sarah is a horny almost 16 year old who's first, only boyfriend dumps her right before her family takes their annual trip to the coast. She's know Tucker forever, and they dated for a year before he left her for the popular girl he was tutoring. He accuses her of just observing the world, as she is completely wrapped up tracking the path of a comet. Sarah is irate, and decides to perform a different experiment - on herself. She starts acting like her older sister Scarlett, taking her clothes, copying her attitude, and soon attracts the attention of a local boy named Andrew. Andrew is 19. They fall in love and their relationship gets really serious, real fast and things come to a head at her sister's fancy going away party.

This book made me uncomfortable. I wanted to like Sarah, who was often delightfully quirky, but she made horrible decisions and was a COMPLETE teenager. Whiny, petulant, and a huge liar. There was a lot of descriptive sex acts (this may be my first YA book with described oral sex performed on a girl) which is fine, but the fact Sarah was lying about her age made me queasy. I felt bad for the guy.

I think teens will really like this book, but I'd rather hand them Forever by Judy Bloom (which this book is described as being the modern version of).

Not really for me, but in the hands of older teens it would make for a good conversation piece if their adult knew the content and discussed it with them.
