I can't believe I never reviewed this on this blog - I've been recommending this book to students for years and all have loved it!
Thirteen babies are found on a plane with no crew, no captain, no adults. No one claims any of the babies and they are put up for adoption. Jonah is one of the babies and has lived a happy, uneventful life until the day when a note is found in his mailbox:
"You are one of the missing."
Another note comes shortly after:
"Beware! They're coming back to get you."
Found is a wonderful dystopian book - read it!
