Query: One of the BEST books I've EVER read! :)

What a great book! I read this book in 4 hours tops and I couldn't put it down! Paks is a strong character, smart and strong. The plot twists and turns, with an unusual dose of surprise every turn. Never a dull moment. BUY THIS BOOK NOW AND THE REST OF THEM TOO!!!!!!!
