Reading Level: Grades 6 and up

Tory Brennan, like her famous aunt Temperance Brennan (who you may know from the TV series Bones), is headstrong, determined, and smart. When Tory finds out that scientists on a nearby island are doing illegal and inhumane experiments on a wolfdog, she and her three best friends Hi, Shelton, and Ben, break in to the lab and rescue the pup.

The poor dog's been infected with parvovirus, a disease common in puppies that can be fatal to dogs, but is harmless to humans. But as Tory and her friends nurse Coop back to health, they begin to notice some changes in themselves. Could Coop's strain of parvovirus have been an experimental version? Could the four kids have caught it themselves?
