Pendragon - Journal of an Adventure Through Time and Space / Official Website / D.J. MacHale. Another worthy kids series along with the Artemis Fowl collection which this reminds me of quite a bit because it features smart kids as opposed to not very bright ones. Ones with a sense of humor. I just love the back and forth across the worlds. Anyway, Book 1 was good, we'll have to see about the rest.
