Two best friends. Two very different grandmas. One epic switcheroo.

Lily's house is a whirlwind of chaos, dirty socks, and forgotten homework. Max's world? A spotless fortress run by the fearsome, no-nonsense Grandma Eugenia. But when a school project sparks the idea of a "Senior Exchange Program," the kids hatch a wild plan: swap their grandmas for two weeks.

It was supposed to be simple.

Granny Dot-with her loud laugh, prankster ways, and love for junk food-might be just what Max's uptight household needs. And Grandma Eugenia-with her strict schedules and endless rules-might finally bring order to Lily's life.

But when the grandmas recognize each other from a mysterious past neither kid knows about, everything unravels. Secrets, rivalries, and a decades-old promise come bubbling to the surface. Now, Lily and Max must figure out what really happened between their grandmothers-before the swap turns into a full-on family feud.

Hilarious, heartwarming, and full of twists, Operation: Grandma Swap is a middle grade adventure about friendship, family, and the unexpected magic of second chances.
