From Emmy, Grammy, Oscar, and Tony winner Viola Davis and New York Times-bestselling publisher, editor, and author Lavaille Lavette comes an action-packed series filled with humor, heart, and undercover hijinks!

Discovering your grandma is a spy is easy. The hard part is proving it…and staying alive in the process.

When Jazzlyn discovers that her estranged grandmother is moving in, she's beyond frustrated. Being 13-years old is hard enough with an annoying brother and an overbearing mother — and now she must deal with a grandma who is taking over her bedroom?!

Jazz has better things to do like hanging out with her best friend, getting stellar grades, and of course, finding the perfect dress – and the perfect date – for the Sadie Hawkins dance. She has big goals and doesn’t need grandma cramping her style.

Before long, Jazz starts to notice peculiar things Grandma does like sneaking out at night and popping up as a substitute phys ed teacher at school. Her instincts tell her that Grandma Mae is up to something, and she decides to prove it. One night, Jazz follows her grandmother into the city and the adventure begins. Caught up in a world of high speed car chases, a ninja fight in an alley, a kidnapping at the school dance, and mysterious money transfers, can Jazz prove her grandma is a spy?

As for Mae, laying low isn’t exactly her strong suit, and, she discovers, neither is playing a grandma. Keeping her nosy granddaughter in the dark is child’s play. But an old nemesis has returned and is on the hunt for Mae’s whereabouts. Can she keep her family safe and separate from her secret life… before it’s too late?
