It is difficult to describe this book without making it sound completely generic: two normal kids are transported by a magical object into a fairy-tale realm where they must must make their way through dangers to a final confrontation with an evil queen. There are supporting characters, good and bad, including talking animals. Yeah, this has all been done before. Originality is not a strong point here. But if you like this type of fantasy this is a reasonably well-done example: It is entertaining and moves along quickly. Leo and Mimi could stand a little more depth, but they are believable as kids and behave appropriately for their ages, not accomplishing any unrealistic deeds of cleverness or martial prowess. Rodda manages a good balance between danger and not being too scary for younger readers.
