This book is one of those giant books which did discourage me slightly from finishing the series. Not that I did not enjoy it, but I must admit this book starts off slow and in the beginning it is a bit difficult to figure out the direction all the different plots are taking. 
 However the author kept dropping tiny hints as he always does before the beginning of every chapter, which keep the reader interested in discovering more, as if uncovering yet another piece of the jigsaw puzzle of the mythology behind the trilogy. Sanderson really knows how to tie all loose ends perfectly.
