A humorous story about a kooky, eccentric, off-the-wall grandmother named Martha May McKenzie, who appears to be a simple coffee shop owner at first but is, in fact . . . A WITCH! Now, Martha is no ordinary witch. Her coffee shop, known as The Witches Brew, is where she hides in plain sight, helping grandmothers with their naughty little grandchildren. She is wacky and weird and completely unconventional, even by witches' standards. As a grandmother witch, Martha wants to use her magic to try and lift the spirits of her two grandchildren (Trinity and Lucas), who have drifted from each other after they experience the tragic and sudden loss of their dad. However, they have no idea that their Grandmother is a witch to begin with! So, Martha will be revealing her secret to them for the first time ever . . . but was it a secret? Jamie (Martha's daughter) has always known that her mom identifies as a witch but has never truly believed her to be one. She begs her mom not to fill her kids' heads with the same nonsense she filled hers with, but Martha doesn't listen. Using her magic, she goes ahead with her "perfect plan." Unfortunately, things don't go as Martha hoped, and in a single Saturday morning, everything quickly spirals wildly out of control, unlocking magical events that take them back through time on the unwanted adventure of a lifetime. Together, they must try and find a way back home, that is, if they can survive what lies ahead, as well as each other.
