The Dirty Streets of Heaven - Tad Williams
I am always amazed by this particular author's world building, lore and story. Tad William's ideas are unique. Often I read a book where the lore or plot or even a character seems to be simply a re-imagination from another book - this NEVER happens with a Tad Williams story.

I think this is the first book in a series and I am looking forward to next installment with enthusiasm.
