It's springtime in Raven Hollow, Pennsylvania, and the entire town is abuzz about the new barn coming to the Beauregard Orchard that will sell apple based pastries and hot apple cider. But when Cori Kerrigan goes out to the orchard to interview Jacoby Beauregard about the new project, they stumble upon the dead body of the construction foreman. The same man Jacoby very publicly argued with just days prior.

But dead bodies aren't the only thing hiding in plain sight at the orchard. An underground hideout, thought to go back to the days of Prohibition, is also uncovered which leads to even more questions, and even more deaths.

In order to solve the mysteries Cori, with the help of her librarian best friend, Maggie McBride, and boyfriend, Ray Dresden, will have to unravel the growing list of clues and suspects before they find themselves underground for good.
