Welcome to Bristlecone, Colorado--home of skiing, snowboarding, and secrets.

As if navigating the eighth grade weren't challenging enough for twelve-year-old spy aficionada Ophelia (Phee) Mahoney, she's caught in an avalanche of trouble when she investigates a classmate's disappearance on a school ski trip and a hit-and-run that leaves a friend in a coma.

The town's sheriff, who's also the father of Phee's crush, considers the hit-and-run an accident, but Phee thinks a sinister motive was behind it. Aided by her friends, Jeopardy!-obsessed Joshua and jockette Kimiko, Phee puts her life on the line to bring justice to her home town.
