The Chariot of Queen Zara

This is definitely one of the books where you can't read them out of order. There's too much that you would need to know from prior books. Still, I'm very impressed by the inventiveness in these books. I don't remember if I ever read this far into the series as a child (our library system made it difficult to get ahold of the next book quickly due to their request system so I moved onto other books) but I'm definitely enjoying it. I just wish I could read them in order!
