Book 1 of the Copernicus Legacy series. This book is reminiscent of the 39 Clues series. Fast pace, lots action / near misses. Barely escaping the bad guys. Kids vs adults in following the clues to the prizes. This YA series would play well for fans of 39 Clues. If you have an adventure loving YA in your life, this would be a good one to have them try out.
