"Great for road trip with the kids."
Great books. Lots of fun, well written, original, unpredictable. We got it for the long drive to drop off my older son at scout camp. We all enjoyed it-- both my sons (ages 6 and 12) really got into the story, and so did mom and dad. We paused the playback from time to time to make guesses about what was going to happen and how it would end, but no one successfully predicted the ending. All in all, a big success and I'm glad there are 4 more in the series. Solves the problem of what books to get for the family vacation this summer.
