Sixteen-year-old Wendy Wyman is bereft over the death of her best friend, Peter Preiss, whose body has been found at the bottom of the town lake. She blames herself because she allowed him to go back to his family’s lakeside boathouse late at night where they had just made love for the first time. She wonders what she could have done differently to stop Pete from being killed, and thinks back to the beginning of the school year when her whole life changed forever.
Wendy will stop at nothing until she finds out the person responsible for killing Peter, who was bullied by most of the students in their junior class. She is in for even more of a shock when she finds out that not only did Pete keep dark secrets from her, but a few of her close friends are hiding ones as well. This also includes Dylan Mayone, the new popular boy at school, who wants her for his own, and may have had a hand in Pete’s death.
