On Whidbey Island, Washington, fourteen-year-old Casey has two goals--to become an excellent basketball player like her mother was, and to find the hit-and-run driver who injured her and killed her mother nine years earlier. Nine years ago, a hit-and-run driver killed Casey's mother. Casey swears revenge if she ever finds out the identity of the driver. Complicating her feelings, every year on the anniversary of her mother's death, Casey receives an anonymous envelope full of money. Is it blood money from her mother's killer? Casey, who shares her mother's passion for basketball, is busy with practice and her new team. Still, she finds time to spend with her beloved neighbor, Megan, who helped care for her when she was younger, and with Megan's daughter Dulcie. When it looks like Megan's computer might contain a clue to the identity of her mother's killer, Casey feels confused and betrayed.
