The story is told from multiple perspectives, of vastly different siblings. Finn, Mouse and India are in danger of losing their house. Their mother, finally accepting foreclosure, sends the siblings on ahead to their uncle's house while she finished out the year in her teaching job. Pockets of hilarity are inserted everywhere, as the characters shine in their own distinctive way. Mouse, the youngest, tries to fill her suitcase with the materials for a science project volcano and chaos ensues as they try to go through airport security. It's these little episodes of brilliance between the masterfully developed characters which really bring the book to life in the reader's hands.
After landing at the wrong airport, Mouse, Finn and India are lured into their own perfect homes. Only if they learn to work together using their differences can they escape Falling Rock and go home. The question that Choldenko balances to the very end is... do they want to go home?
