After losing her husband in a terrible car crash, thirty-five-year-old Kate is left to pick up the pieces of her life alone. Although she has physically recovered, she worries her spirit never will. But when she learns that she has inherited a fruit orchard in a small town just outside Gettysburg, Pennsylvania, from her great uncle Stan, she takes this as an opportunity ripe for the picking. Kate knew immediately what to do with it: open a cider house. Her hopeful plans fall far from the tree when she finds the body of the orchard manager, Carl Randolph, leaving her to figure out who is at the core of this murder.

She had been in correspondence with Carl, who had agreed with her brilliant idea of opening a cider house. But not everyone is so quick to buy what she was selling--Uncle Stan's lawyer, Robert Larabee, paints a less rosy financial outlook of the orchard's past, present, and future.

Kate discovers that Carl had large, unexplained deposits to his bank account and it becomes clear that either he was blackmailing someone, or someone was paying him to keep quiet. Meanwhile, Kate and her neighbors receive offers to buy their property from a mysterious buyer. And there's more than meets the eye with the neighboring orchard owner, Daniel Martinez, although Kate can't quite put her finger on if it's sweet or sour.

Will she be able to pick out the bad apple among the bunch before it's too late?
