An amazing book. While the description tells you what the book is built around, it's who you're reading about that really makes this wonderful. A whole host of well-developed, distinct and compelling characters, dealing with fascinating issues.
Very much agreed with CGMullin on this - there's a reason I'm still re-reading these years after they were first written! They've held up extremely well, and get better the more you know the characters.
It's heartbreaking and wonderful. For anyone who's looking at the reviews but hasn't read any of the series, PLEASE start with #1. Though this finale is breathtaking, it won't be nearly as powerful if you haven't read the earlier books.
