Life appears peaceful on Loggerhead Island – rescued from financial disaster, the research institute is flourishing once more. But the tranquility is quickly shattered when Tory Brennan and her technophile gang discover a mysterious box buried in the ground.

A seemingly innocent treasure hunt soon turns into a nightmarish game of puzzles, as it becomes clear that one false move will lead to terrible, explosive consequences.

The clock is ticking. Can Tory and the Virals crack the code in time to save the city – and their own lives?

Tory Brennan, niece of acclaimed forensic anthropologist Temperance Brennan (of the Bones novels and hit TV show), is the leader of a ragtag band of teenage "sci-philes" who live on a secluded island off the coast of South Carolina. When the group rescues a dog caged for medical testing on a nearby island, they are exposed to an experimental strain of canine parvovirus that changes their lives forever. As the friends discover their heightened senses and animal-quick reflexes, they must combine their scientific curiosity with their newfound physical gifts to solve a cold-case murder that has suddenly become very hot-if they can stay alive long enough to catch the killer's scent. Fortunately, they are now more than friends: They are a pack. They are Virals.

Since their dangerous transformation, the Virals have been lying low. But now Loggerhead Island is at risk, and with it, their parents’ jobs. The pack suddenly faces separation. The only thing that can stop it is money, and lots of it.

Never one to shy away from a challenge, Tory Brennan, great-niece of famous forensic anthropologist Tempe Brennan, thinks she’s devised the perfect plan: find the lost treasure of famous she-pirate Anne Bonney. Legend has it that Bonney hid her fortune somewhere near Charleston, but in nearly 300 years no one has found it.

With the help of newfound powers, and a nudge from modern technology, the Virals are on the right track. But they’re not the only ones looking, and whoever is following will stop at nothing to recover the treasure first. Adding to the danger, the Virals soon learn that Anne Bonney didn’t leave her booty unprotected. And there are dead bodies to prove it.

The path ahead is fraught with danger. And this time, the pack’s special abilities may not be enough to save them…
