It's autumn in Painter's Mill, and fourteen year old Katie Burkholder has been tasked with picking apples in Zimmerman’s Orchard with her brother. It’s just another day filled with chores—until her best friend Mattie arrives to help. Somehow, boredom transforms into fun and games whenever the girls are together. The innocent fun comes to an end when Billy Marquardt and his gang of friends interrupts. Katie is no prude, but she knows better than to associate with the older English boys, especially since they’re known troublemakers. Mattie has no such compunction. Thumbing her nose at the Ordnung and all of the Amish rules, she disappears into the old barn with Billy.
It is about a famous soap star, Rick Arlen. He is recieving death threats and when Nancy and Bess have to investigate Bess goes mad over him. Bad things are happening and if Bess is at his side almost non-stop she is in danger too. Mattie is very upset and Nancy has to hurry before Rick's killer does get him.
No one is more surprised than Mattie Spenser herself when Luke Spenser, considered the great catch of their small Iowa town, asks her to marry him. Less than a month later, they are off in a covered wagon to build a home on the Colerado frontier.
