This children's science fiction book is filled with excitement! 13 year old Jonah was adopted as an infant and it never seemed to be a very big deal to him except that his parents always embarrassed him by telling the story of the 'miracle' of his arriving in their family. Then Jonah starts receiving strange letters; the first one says "You are one of the missing." and the next one says "Beware! They're coming back to get you." Jonah and his younger sister Katherine race against time to find the truth behind Jonah's adoption and stop a disastrous chain of events that could change history and/or alter the future. This adventurous book deals with family and friendship struggles as well as mystery and time travel. It was so much fun that I have already requested the sequel from the library (Sent by Margaret Peterson Haddix.)
