About This Book

Themes
Quick Assessment
A malfunctioning iPhone sends Mel and two schoolmates back to Christmas 1776, where they must help George Washington cross the Delaware River and keep American history on track. The tone is humorous and fast-paced, with time travel, historical detail, and Benjamin Franklin as a memorable figure, and it includes battlefield-era setting but no graphic content. Parents can expect light peril and some wartime backdrop handled with lightness, making it a comfortable pick for middle-grade readers who enjoy history-based adventure.
