No Passengers Beyond This Point (Dial Books for Young Readers, 2011) by Gennifer Choldenko is a fantasy that makes you wonder along with the characters.
It starts out when Finn, his older sister India and his younger sister nicknamed Mouse are sent off to live with their Uncle Red because Mom has lost the house. But instead of getting to Colorado, they end up at this strange place called Falling Bird. They can become citizens, or Finn could work for Sparky, or go on to Uncle Red's. What should they do? Each has a different opinion.
The story is told in multiple viewpoints. I like what happens with all the characters, but confess that Finn is my favorite.
I've been a Gennifer Choldenko fan for years, so knew I was getting something good when I got this book. Check out her other books here. Here's the book trailer for No Passengers:
