Query: Read the reviews for Olympos before you buy this

I really enjoyed this book, but I would not recommend it to anyone. The ending is a cliffhanger, and if you enjoy this book you will feel compelled to read the sequel, Olympos. The sequel is a complete disappointment -- read the reviews and see what people say about it. Although reading Illium was fun (although it dragged in the beginning), the overall experience of the two books was negative. I wish I'd spent my time and money on something else.
