The Virals are put to the ultimate test when they find a geocache containing an ornate puzzle box. Shelton decodes the cipher inside, only to find more tantalizing clues left by "The Gamemaster." A second, greater geocache is within reach--if the Virals are up to the challenge.

But the hunt takes a dark turn when Tory locates the other box--a fake bomb, along with a sinister proposal from The Gamemaster. Now, the real game has begun: another bomb is out there--a real one--and the clock is ticking.

"If you like Bones, you'll love Virals" James Patterson "Kathy Reichs gets it dead right with sharp writing and a plot that throws a bunch of very real teens into a deadly adult world ... I loved it and I'm sure fans of Alex Rider will love it too" Anthony Horowitz "Mystery ... fantasy ... science ... and heart-stopping action - this book is DANGEROUS. After I read Tory Brennan's first adventure, I wanted more, more, MORE" R.L. Stine, author of Goosebumps
