Fans of Michael Vey will not be disappointed in this high-octane addition to the series featuring a boy who can manipulate electricity and who tries to stop the nefarious Dr. Hatch from controlling the world's power. Picking up from the final escape scene in Rise of the Elgen (2012), Michael finds himself in the Amazon rain forest. There, he joins forces with Tessa, whose ability to amplify powers comes in handy as they try to free the other Glows still held captive. Evading both the Elgen and Peruvian armies, the teenage Electroclan try to stop Dr. Hatch and return home once and for all. While the character development is shallow and the dialogue sounds dated, Michael and his friends are appealing, uncomplicated protagonists. Chaste romantic scenes and a conspicuous lack of profanity may widen the audience. Readers new to the series may be confused by the large cast and lack of backstory, but the relentless pace and constant one-liners should keep the pages turning easily.--Hayes, Summer Copyright 2014 Booklist
