The Anachronistic Code: Memories from Tomorrow

It’s 1985, and Josh Donegal is seventeen again … and he’s being watched.
Josh has decoded a message from the future, but he’s about to find out that there’s a group that doesn’t want him to follow the clues it’s pointing to. That’s not his biggest challenge though. He still has to figure out how to tell his parents that he's leaving and how to say goodbye to the girl he left behind the last time.
