Gr 7-9-Months ago, 14-year-old Tory and her friends accidentally acquired supernatural abilities while attempting to solve a decades-old cold-case murder. Now, the group has discovered a geocache, left behind by someone they know only as the "Gamemaster." The Gamemaster leads the gang on a scavenger hunt peppered with puzzles, codes, and riddles. As the treasures they find become increasingly dangerous, Tory and her friends suspect that one geocache may be a ticking time bomb. The Virals must race against the clock to find it before it detonates and kills innocent people. While this sci-fi/mystery mash-up has some plot inconsistencies and implausible moments, it will appeal to fans of the first two books. The four Virals-Tory, Shelton, Ben, and Hi-are well defined in the course of the story. Though they are all intelligent and protective of one another, their actions are not always prudent or legally sound. The group's "save the world" mentality thrusts them into plenty of perilous situations, and simply letting law enforcement handle the Gamemaster is never a real consideration. Still, the friends admirably stick together and will stop at nothing to protect the innocent.-Leigh Collazo, Ed Willkie Middle School, Fort Worth, TXα(c) Copyright 2013.
