Following the shocking events of the previous weeks when Tory Brennan, niece of forensic anthropologist Tempe Brennan, and her group of disparate friends discovered that they had somehow been struck down with a canine disease that had changed their DNA, and given them powers that they could neither control nor understand, they have lain low.
But with their home under threat and the prospect of separation all too real, they need to find a way to preserve their group. But only one thing will save them: money. And lots of it. And as far as Tory can see, there is only one way they can get enough money quickly: they must find she-pirate Anne Bonney's legendary treasure.
Rumour has it that she hid it in Charleston, but in over 200 years no one has been able to find it. But with the help of their new-found powers, the Tory is amazed to find that they might actually be on the right track. The problem is they aren't the only ones looking for it, and if that wasn't dangerous enough, Anne Bonney booby-trapped the trail every step of the way, and there are bodies to prove it.
One way or another, the path ahead is fraught with danger. And this time, their special powers may not be enough to get them out of trouble...
