No Passengers Beyond This Point by Gennifer Choldenko; 2011. Hardcover. (Ch-FIC)

Three siblings - India, Finn, and Mouse - have less than forty-eight hours to pack up all their belongings and fly, without Mom, to their uncle Red's in Colorado, after they lose their house to foreclosure. But when they land, a mysterious driver meets them at the airport, and he's never heard of Uncle Red. Like Dorothy in Oz, they find themselves in a place they've never heard of, with no idea of how to get home, and time is running out. In a total departure, Gennifer Choldenko tells a story of adventure and survival, set in a fantastical place with rules all its own. Sharp dialogue, high stakes, and taut action make this a book that will stick with you long after you read the incredible ending..
