Query: Best in the Dark Tower Series!

All of my doubts about the Dark Tower Series completely disappeared once I read this fourth installment of Roland's story. This compelling prequel finally answers some of the questions of Roland's past. You can learn all the secrets about Roland's friends and his family, plus an entertaining love story develops between Roland and Susan Delgado. The bad characters are pure evil, and the good characters make you laugh and cry. I couldn't put it down on a FIVE-HOUR plane trip!The book is very easy to get into because the beginning scene on the brainy train Blaine is one of the best sequences I have ever read. I read that chapter a few times because I liked it so much. The Wizard of Oz references are placed well, and it's fun to figure them out. This book is a great romantic fantasy!
