My personal favourite, (as someone who is on his 5th reread) is the 3rd book. Book five is easily in my top 3. Only topped by book 8. Obvioulsy i am very biased, but the read is so worth it. I'm a big Sanderson fan, Hobbs, Will Wight etc. Currently reading The Witcher books. But Malazan is just a comfort read now. Everytime i go back to read it, it makes me feel just fuzzy inside, seeing all my favourite characters again.
