This is The Malazan Book of the Fallen

After I wrapped up "The Curse of the Mistwraith" I went back to read "Midnight Tides". Brew green tea, sit down. Read ten paragraphs or so, then... think for the following hour and half without reading another line.

That's what it does to me. More and more characters give voice to my own thoughts and feelings. Blurring, because I can't say anymore if I developed a line of thought on my own, or sparked by something I read. Often I find characters say something I thought a moment before, and often I go to reread some old page and find again some thought I believed my own.

Seren longed to hold on to that long view. She desperately sought out the calm wisdom it promised, the peace that belonged to an extended perspective. With sufficient distance, even a range of mountains could look flat, the valleys between each peak unseen. In the same manner, lives and deaths, mortality's peaks and valleys, could be levelled. Thinking in this way, she felt less inclined to panic.

From Deadhouse Gates:

What see you in the horizon's bruised smear
That cannot be blotted out
By your raised hand?
