This was a cute and amusing novel aimed at middle graders and younger. It's an easy and fast read, and it's very well-written. It has a layer or two in it, which is unusual for this level of writing, so I was also pleased with that. Rooted loosely in the story of Hansel and Gretel, these two young kids, 11-year-old Solomon, and 8-year-old Constance find themselves suddenly uprooted and moved to a new town for no apparent reason, but the reason does become apparent to them and quite scarily so. Their new next door neighbor is a witch - and not a pleasant one. She's known for eating kids, and their dad, who happens to be a twin, and his new wife, their stepmother, want the money that's supposed to come to the kids.
We're told that Sol is the smart one, and Connie not so much, but she's a sneaky, scheming little devil, and a mischievous one, too. I liked her! Together they decide that they must take on this witch, and when Connie is captured by her, Sol becomes frantic. Fortunately, his science smarts enable him to take a logical approach to discovering where the witch is hiding his sister.
As I said, the book is well-written, but there was one issue I encountered which is worth exploring from a writing PoV. A few days ago I reviewed a book about punctuation, and mentioned at the time that not a few professional writers might make use of it, and I read a part of one sentence in this book which revealed how important smart punctuation is: "Holaderry and Connie, tied up" was what the sentence said in part. Holaderry is the witch. She has Connie tied-up, but the placement of the comma here suggests that both were tied-up! It should have read, "Holaderry, and Connie tied up."
Just nudging that comma over to the left by two words makes a lot of difference. The classic example of how the placement of commas can change a sentence is this: "Smith says Jones is an ass" versus "Smith, says Jones, is an ass." The addition of those two tiny commas gives the whole sentence the opposite meaning! It's worth remembering as a writer.
But that was a minor issue. Overall I consider this novel to be a very worthy read and I recommend it.
