I read the book, Found, by Maragret Petersen Haddix not too long ago and I highly recommend it if you’re looking for a good read that’s really captivating. I couldn’t put it down. It’s about an adopted boy who suddenly receives mysterious letters from an unknown address. He and his friend, who has a secret, have to solve the mystery together, along with the boy’s sister. They look through secret documents, lists of phone numbers, and unfocused pictures. And in the end, they discover how all of this started. Their lives, which were once basketball tryouts and homework became a mystery of time travel and who they used to be. But you’ll have to read the book to find out more. There are two following books, and I don’t know if there are more, but the second one is called Sent, and the third one is called Sabotaged. Enjoy!
