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!

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.

It's June in Montreal, and Dr. Temperance Brennan, who has left a shaky marriage back home in North Carolina to take on the challenging assignment of Director of Forensic Anthropology for the province of Quebec, looks forward to a relaxing weekend in beautiful Quebec City. First, though, she must stop at a newly uncovered burial site in the heart of the city. The remains are probably old and only of archeological interest, but Tempe must make sure they're not a case for the police. One look at the decomposed and decapitated corpse, stored neatly in plastic bags, tells her she'll spend the weekend in the crime lab.

When Ava arrives at Brodie’s Watch, she thinks she has found the perfect place to hide from her past. Something terrible happened, something she is deeply ashamed of, and all she wants is to forget. But the old house on the hill both welcomes and repels her, and Ava quickly begins to suspect she is not alone. Either that or she is losing her mind. The house is full of secrets, but is the creeping sense of danger coming from within its walls, or from somewhere else entirely?

Three very different women come together at isolated Baikie’s Cottage on the North Pennines to complete an environmental survey. Rachael, the team leader, is still reeling after a double betrayal by her lover and boss, Peter Kemp. Anne, a botanist, sees the survey as a chance to indulge in a little deception of her own. And then there is Grace, a strange, uncommunicative young woman hiding plenty of her own secrets.
