It's harvest time in Chiqetaw, Washington; Emerald O'Brien's favorite season. But this year, nature yields a most supernatural bounty. When Em and her sweetie, Joe, stumble over a bramble-covered foundation that has remained hidden for fifty years in the lot next door, strange events begin to occur. The cat vanishes. Will o' the Wisps threaten to harm Emerald and her loved ones. And the ghost of a woman named Brigit and her beloved calico make themselves at home in the backyard. Now it's up to Em and her friends to delve into the past, reveal the secrets of the dead and lay them to rest as they ring in the autumn with a harvest of bones.
