It's about a boy named Zac or agent Rockstar. A B.I.G. agent was in the G.I.B. hideout so Zac was sent to find him or her. Zac went to 1-62 levels to find the mole. Zac was attacked by lots of G.I.B. agents! I give this book an eight out of ten because it was a great book but not an excellent book.
