Sanderson would be.....ugh this is hard. Sazed ascending I think. It's just so mindblowing, I had to read it twice because my mind couldn't comprende.
Edit: Non-Sanderson..... Hmmm, I guess Rand coming back doesn't count....Maybe the end of The Stone of Farewell, you know Memory, Sorrow, and Thorn. If you guys didn't notice, I'm a big fan of that trilogy.
