Lost treasure. Perilous adventures. Deadly foes. Tory and her friends are just starting to get a handle on their super-heightened wolf-like capabilities—contracted during a medical experiment gone horribly wrong—when they find out funding is being pulled from the institute where their parents work. The pack now faces its greatest fear—separation. So when Tory stumbles across ancient lore hinting at a lost pirate treasure, the Virals devise a risky plan that pits them against fiendish traps, headless corpses, and deep underground tunnels. But they're not the only ones looking, and the competition could be lethal. They'll need to work as one mystery-solving canine force if they to hope to uncover the lost fortune, save the institute, and stick together!
