Boys of Summer by Jessica Brody, is a nice contemporary story with a bittersweet ending. The story is told from the perspective of three guys, Grayson, Mike and Ian. Boys of Summer is a book that follows these boys through a summer on an island where secrets and emotions get in the way of their friendship. It's the summer between high school graduation and the start of their new lives.
Mike, Ian, and Grayson have been friends since they were children and have always spent the summers together on an island. However, this summer each boy is dealing with their inner turmoil. Ian just lost his father, Mike has to help his family pay the bills by taking on two jobs, and Grayson is hiding an injury that can ruin his entire future. We follow each boy this summer as they deal with each problem. Their lives are still connected in some way before going out into the unknown and leading separate lives.
I think it's a bittersweet story because of how realistic the story is and when the summer comes to a close, the boys are still figuring things out, but at eighteen, they still have their entire future ahead of them. *JK*
