Not Just a Witch by Eva Ibbotson

Daniel’s parents, brainy professors, don’t pay him any mind (except for the times when they check his mind to see if he’s smart enough? Is he the best in school?)
Daniel, unfortunately, is ordinary. Well, not completely. He takes up with a coven of witches, who also aren’t ordinary. They all mean well, but often get muddled.
Not Just a Witch is broad comedy. There’s a devilishly handsome villain who hoodwinks two of the lonely witches and uses their talents for terrible purposes.
The vocabulary can be challenging, but it’s worth it. Illustrations help the struggling reader keep going.
So, if you know anyone age 6 and up, who needs a charming “pick me up,” pick up Not Just a Witch.
