I've been reading the Harry Potter series with my older kids, and I started this book looking for another children's series that I could devour. Unfortunately, this wasn't it for me. That's not to say that I didn't enjoy this book. I did! It was creative and clever. But I never felt like I just couldn't put the book down. That being said, though, I did look forward to reading it. It's just that I felt like I could read a few chapters here and there, and be satisfied for the time being. I suppose I was hoping for big mysteries and marvels in the story, but the problem the children were given to solve just wasn't overly interesting to me. I did enjoy reading about the children and how they interacted with each other. I liked that that they each brought their own gifts to the group, and they wouldn't have been able to succeed without each other. I think my kids would enjoy this book, and I'll probably continue on with the series.
