Found

by Margaret Peterson Haddix

Summary: Jonah has always known he was adopted. His friend and neighbor, Chip, finds out that he is, too, in a very unsettling way. They are both receiving frightening letters that warn them they are among the "missing." Jonah, his sister, and Chip go on a high-tech adventure to find out who else is among the missing, and how to stop a catastrophe that could change the entire world!

My thoughts: If you're looking for a quick, exciting read, this is the book for you! Found is the first book in a planned trilogy.
