Gr 6–10—This sequel easily lives up to the promise of Virals (Penguin, 2010). When exposure to an experimental parvovirus led to enhanced senses and strengths, Tory and her friends were both frightened and exhilarated by their newfound abilities. As this novel opens, their powers seem to have stabilized and their lives have returned to relative normalcy. But financial woes threaten the closure of Loggerhead Island Research Institute where most of their families work. As their parents begin making plans to move elsewhere in search of employment, the four teens realize that they may be separated for good. When they stumble across a lead to the long-lost treasure of pirate Anne Bonny, they devise a daring plan to save the foundation and stay together intact. With its meld of science, intrigue, high-tech sleuthing, treasure hunting, and daring midnight adventures, this novel is hard to put down. The complete cluelessness of the adults may annoy some older readers but teens will be amused and pleased to know that what they've always suspected is, in fact, true.—Jane Henriksen Baird, Anchorage Public Library, AK
