Rating: WARTY!
This was an audio book written very much in the vein of the Harry Potter series, and it was read by Jim Dale. This, I think, is where the two-fold problem with it lies. It's too much like Harry Potter. That problem is not improved by having Jim Dale read it! I'm a big fan of Jim Dale and he has a mellifluous voice, but having him read a novel which has such a lot owed to HP made it seem like a rip-off. It's a junior Harry Potter without the better HP qualities, namely that adults could enjoy it as much as kids did.
The first few minutes I was listening to it, I kept having to remind myself that it was not Harry Potter, but that became easier as the story progressed, because this is very much written for middle grade and it was neither entertaining or appealing to me. There was far too much predictability and trope. Just as in HP, Kate, Michael, and Emma (the equivalent of Harry, Ron, and Hermione) are orphans who meet up with an elderly wizard (the equivalent of Dumbledore) and have magical adventures in pursuit of some horcruxes - er magical books.
Despite now starting book two (I haven't read book one, note) and being exposed to all manner of magic and magical creatures in that volume, when these kids meet up with the professor again, and he takes them to another place by traveling through a cupboard, the kids are amazed and surprised that they enter from one location and exit to another place entirely. Which part of "WIZARD" is it they don't get? This told me that these kids are morons, and I had no further wish to read of them. The fact that the professor was an information hog, telling these poor kids next-to-nothing made me detest him as much as I detested the real Dumbledore. This series may interest incurious kids of the eight to ten range, but I can't imagine older kids - who have any kind of imagination at all - finding anything really new or entertaining here. I cannot recommend it.
