This book is about a 12 or 13 year old kid whose name is Jonah. Jonah  knew he was adopted, but his friend Chip did not know that he was adopted! They started to receive weird letters from people that they didn’t know because they didn’t have any return adress.  Jonah and Chip started to get mysterious about their real identities and where they came from. But, when they try to find out who they are the FBI would not let them know anything about themselves!  I WISH THAT I COULD SAY MORE BUT IF I DO I WILL SPILL THE BEANS! So instead why don’t you read the book yourself.
