Anne Shirley is all grown up, married to her beloved Gilbert, and now a mother of six mischievous children. These boys and girls discover a special place all their own, but they never dream of what will happen when a strange family moves into an old mansion nearby.

The Meredith clan consists of two boys and two girls—and a runaway named Mary Vance. Soon, the Merediths join Anne's children in their private hideout, intent on carrying out their plans to save Mary from the orphanage, help the lonely minister find happiness, and keep a pet rooster from the soup pot.

There's always an adventure brewing in the sun-dappled world of Rainbow Valley.
