Local legends speak of a Cadburn daughter who ran off to fight in the Civil War, disguised as a boy, and never came home. Other legends tell of a girl's ghost, in Civil War costume, haunting Cadburn Creek. And then there are the stories of Underground Railroad tunnels going from Cadburn Creek to suspected station houses. But no one has ever proved those stories true.

Three years ago, those rumors mixed with the usual wrangling between the two rival historical societies in Cadburn Township, complicated by the activities of the Spirits of '62, the local Civil War reenactors group, and the bickering between their leader, Steve, and Lyndsy, a history student hoping to make a name for herself, no matter the cost.

Olivia, head barista for Book & Mug, finds herself in the middle of everything, when Lyndsy rents a room in the same historic home and stirs up trouble with an old man obsessed with the Cadburn ghost. She and others breathe a sigh of relief when Steve and Lyndsy leave town abruptly, and the political in-fighting seems to be resolved.

Until an unusually rainy fall causes flooding in Cadburn Creek, revealing the rumors of tunnels to at least be true. When secrets buried for three years are uncovered, the rumors and rivalries and bickering return to the light of day. Saundra, Kai, Eden and Olivia join forces to separate truth from rumors and let the dead rest at long last in peace.
