Doing a complete re-read of Malazan Book of the Fallen, and onto the second book.
It is a fantasy series, yet has a much deeper setting then you get in most fantasy series and it doesn't have the whole "good wizard defeats evil orcs" tropes common to the genre. The book is not the easiest to read, dropping you in headfirst. Many people have said the first book is the hardest to read too so many reads are discouraged from continuing, yet I feel it is worth the effort.
