Code is the third novel in the Virals series of novels for young adults written by the American forensic anthropologist and crime writer, Kathy Reichs and her son Brendan Reichs, featuring fictional character Tory Brennan, great-niece of Temperance Brennan.
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 reachâÂÂif the Virals are up to the challenge.
But the hunt takes a dark turn when Tory locates the other boxâÂÂa fake bomb, along with a sinister proposal from The Gamemaster. Now, the real game has begun: another bomb is out thereâÂÂa real oneâÂÂand the clock is ticking.
But, unknowingly, one of the Virals has betrayed them. But will the others forgive them?
