Rumblewick is a highly qualified right hand cat to the most unwilling witch in the kingdom. He's contractually bound to shape her into the most well-rounded, disgustingly terrible witch she can be, but unfortunately, Haggy would much rather be a normal little girl than do things like boil frogs and frighten children. Poor Rumblewick! Haggy's antics keep him on his toes, endlessly dodging the wrath of the Hags on High.

Here's the latest problem: Haggy Aggy's made "bestest" best friends in the whole wide world with two very unwitchy girls. And they have asked her to sleep over tonight and she's said YES. That certainly isn't what a witch who WANTS to be a witch does, is it? Through humorously illustrated diary entries that are perfect for emerging readers, Rumblewick details life with Haggy, the loveable witch who just can't get with it!
