Gosh, I'm sorry to disagree with all these reviews, but I really did not enjoy this book. In order to explain why, I have to provide some spoilers, so don't continue if you want to read the book.
First, I REALLY do not want to read about the sex lives of teenagers. This story begins with the couple meeting when they are children and then finding each other again in high school, and we have the whole high school romance thing, which is a little twisted because Mitch has to get over his fear that the relationship will go bad if they go beyond being friends and then when he finally does, Skylar gets cancer.
Two things here, I'm a grown woman, I am not interested in teenage love and sex. This goes on for 15 chapters! Second, there is nothing so depressing as cancer and really puts a damper on love and sex. Mitch's sudden turnaround is never explained. What happened to change his mind so drastically? And then the same thing for Skylar. Why does she drop him just because he going to college in Boston? I mean, seriously? She's going to graduate from high school a year later from him. Boston has more colleges than any other city in the country. Why wasn't there just ONE time when she considered going to college in Boston? Why did she keep saying that they would be separated for four long years? Boston and New York...really not far apart either.
When Skylar dumps him after all Mitch has done for her when she was sick, I was pretty much done. I kept reading, I kept hating Skylar. I kept wanting to get to the grown-up part, but even with Part Two when they were adults, I still felt like these people acted immature and weak. In the end, Skylar and Mitch get back together. That's after Skylar totally screws Kevin over. Yay, happy ending! Seriously? I finished the book. Can't say it was a pleasant experience though.
