Grandma Gang Books

The Grandma Gang book series is inspired by author Cathy Pepe’s brother Donny, who was born with Down Syndrome and taught the family how special life is.

Mary Grace and Donny’s California Adventures: A Grandma Gang Mystery is the first book in the series and tells the story of Donny and Mary Grace moving to live with their grandparents (Grandma Cathy and Papa Steve) on their vineyard near Santa Barbara (which Donny loves – Mary Grace not so much) and their adventures at North School, where they move after living in Wichita, Kansas their entire lives.

In Donny, Mary Grace and the Dognappers, dogs have started to go missing around the siblings’ adopted west coast hometown, including Grandma Cathy’s two dogs – Krug and Kansas. The local authorities suspect that dognappers are responsible for all the missing pets. Who are the dognappers? Where are the dogs and how can they be brought back home? It’s a mystery that only Donny, Mary Grace, and the Grandma Gang can solve.

In Donny and Mary Grace and the Ugly Marbles, Donny and Mary Grace find a set of marbles at the senior living center, but some of them are really ugly and just don’t look right. The siblings discover that criminals are using the senior living center as a base of operations. Only Donny, Mary Grace, and the Grandma Gang can crack the case and prevent the criminals from completing their sinister scheme.

In Donny and Mary Grace Go to Camp, Donny, Mary Grace and the Grandma Gang are brought together once again at an action-packed summer camp in the Santa Ynez Mountains. The children develop a healthy bond with nature while making new friends with fellow campers and a local Chumash Indian. When a camper goes missing during a natural disaster, the mystery-solving siblings and the Grandma Gang are the only ones who can step forward to save the day.
