" I started reading this because my little brother had just read the first few and was in love with them. They are surprisingly good; I've read the first 3 so far, and they combine a good set of characters with around-the-world adventures and a not-just-for-little-kids kind of plot. They are not the most challenging books for me, but they are enjoyable and funny, and I will plan on reading the others in the series. "
