Product Description:

Enter the hilariously dark world of Granny, a children's novel with a wicked twist by bestselling author Anthony Horowitz.
Joe Warden isn't your average unhappy boy—he lives in a mansion, Thattlebee Hall, with rich but uncaring parents. But his real nightmare? His Granny.

She's not just mean—she's terrifying, grotesque, and possibly evil. When Joe starts to suspect that she has a secret (and very sinister) plan involving him, he must uncover the truth and stop her... before he’s turned into neoplasmic slime! Packed with dark humor, thrilling suspense, and a monstrous twist on a beloved family figure, Granny is a horror-comedy for kids that will leave readers howling with laughter—and fear.
