Sammy Kingston, the most popular girl at school, goes to a party one night and dies on her way home. The next morning, though, she wakes up and as the day progresses, she realizes that she's reliving her last day. In one chapter for each day, Sammy lives that day 7 times, each one new and exciting. Sammy's personality changes as she learns each day what is important and how to end the recurrance of the day. This book captured me from the first page and it was hard to put it down. I recommend it for high school aged people.
