In this action-packed series, Carter Lewis and Isabelle Hunter help their computer-crazy uncle who has created a totally new kind of book experience. You don't read Uncle Dan's version of classic books; you live them in a virtual reality simulation. When Uncle Dan realizes someone has hacked his system and is corrupting his books, Carter and Isabelle must work together to help him uncover and beat the hacker. In Book 1, Carter Lewis is thrilled when he gets a coded message from his computer-programming uncle offering him the coolest job in the world -- helping test a new virtual reality program. Carter will even put up with Uncle Dan's other new helper, Carter's brainiac cousin Isabelle. Everything is fantastic until Uncle Dan discovers someone has tampered with the code in The Three Musketeers.
