Ever since Tory Brennan and her friends rescued Cooper, a kidnapped wolf pup with a rare strain of canine parvovirus, they've turned from regular kids into a crime-solving pack. But now the very place that brought them together - the Loggerhead Island Research Institute - is out of funding and will have to shut down. That is, unless the Virals can figure out a way to save it.

So when Tory learns of an old Charleston legend about a famous she-pirate, Anne Bonney, whose fortune was never found, she can't believe her luck - buried treasure is exactly what she needs to save the Institute on Loggerhead! Trouble is, she and her friends aren't the only ones looking for it. And this time, the Virals' special powers may not be enough to dig them out of trouble . . .
