"The most winning junior detective ever in teen lit. (Take that, Nancy Drew!)" —Midwest Children's Book Review Sammy knew that getting to know her new rockstar dad on a cruise would be a little uncomfortable. . . . But when the heiress to a perfume empire disappears from the ship, it turns out everyone's in for a rocky ride. In this penultimate book in the Sammy Keyes mystery series, Wendelin Van Draanen pays homage to the mystery genre. This book is a classic locked-room whodunnit—Sammy Keyes style. The Sammy Keyes mysteries are fast-paced, funny, thoroughly modern, and true whodunits. Each mystery is exciting and dramatic, but it's the drama in Sammy's personal life that keeps readers coming back to see what happens next with her love interest Casey, her soap-star mother, and her mysterious father.
