The Well of Ascension
Author: Brandon Sanderson
I've rather enjoyed this book. Its not as good as the first book in the series, but the writing style was very readable and, unusually, the ending wasn't obvious from page one.
The author does a good job evolving the characters and spins a decent, well thought out yarn. Both of which are often missing in modern fantasy.
If you liked the other books by this author, then you will definitely enjoy this one.
