I considered this a worthy read, but it's the first in a series and I don't think based on this one, that I'd be interested in a series, but then it's not aimed at me; it's aimed at young children who might find it worth their time.
My biggest problem with it was that the story was really not original. It's merely a retread of the Sorcerer's Apprentice story. This guy works for Strega Nona (this term means grandmother witch). One day he sees her make spaghetti using a spell, but he misses a crucial part to turn-off the charm, and so when she's out and he makes his own pasta, it never stops spewing out.
Soon the whole village is being strung along but even they can't eat it all. Fortunately, Grandmother Witch returns in time to stop the issue and then the poor assistant has to eat all this pasta until he is fed up of it.... It was a fun read, but not really al dente enough for me to order a second course.
