The Virals' home on Loggerhead Island is under threat, and only one thing can save it: a lot of money.

A 300-year-old legend

Rumour has it that notorious pirate Anne Bonny hid her treasure somewhere in Charleston in 1720. No-one knows where, but Tory Brennan — great-niece of famous forensic anthropologist Dr Tempe Brennan — is certain that the Virals can work out Bonny's cryptic clues.

A deadly path

It isn't long before the Virals are on the right track. But they aren't the only ones searching for the treasure.Someone is following them, and will stop at nothing to get their hands on it.

Dead bodies litter the trail. Time is running out before the island will be sold.

Will the Virals' special powers be enough to save them?
