Time was, baker Lizzy Tucker didn’t have to deal with anything darker than the chocolate ganache on her cupcakes. Then the surfer-blond, disturbingly charming Diesel entered her life, along with his nemesis, the raven-haired, eerily alluring Wulf Grimoire. They’re both after the ancient SALIGIA stones, which hold the power of the seven deadly sins—and they’re convinced that Lizzy has the extranormal ability to find the stones.

Lizzy and Diesel have already found the “gluttony” stone. Now, on a perfectly lovely autumn day, Diesel and his pet monkey, Carl, whisk her away from her kitchen to a crime scene. Lizzy senses that the body sprawled on the sidewalk points the way to another SALIGIA stone—this time, it’s the “lust” one.

Their search will take them on a desperate, albeit scenic, tour of New England, from the catacombs under Boston’s Old North Church, through the city’s charming Louisburg Square, to the chambers of a centuries-old secret society deep within Dartmouth College.

But Wulf, along with his minion Hatchet, are also on the trail. As the arcane power of the lust stone puts temptation in the path of Lizzy and Diesel, can they keep their focus on finding the stone before Wulf does?
