What do you think of Seirawans new book?

Yasser Seirawans new book, Winning Chess Combinations came out last month. I got it as a gift and briefly glanced through it. For those you that have atleast somewhat thoroughly read it, what do you think of it?

Its the most advanced of his books, I think you should go back and read his winning chess tactics first, I own it, Im about 1/3 of the way through its a nice read, not overly complicated.
