I've read most of the Mistborn books, not including the short stories "The Eleventh Metal", and "Allomancer Jak and the Pits of Eltania", and so far, I love the universe. Like it said in the first book, there's always another secret. The second era books are awesome, but it just doesn't feel the same without a Mistborn. I've spoiled some of the universe for myself, but it only raised more questions, so I can't wait until I've finished this next series. My friend, from before, introduced me to the cosmere earlier this year. He also showed me where I could get the book "Warbreaker", and as of right now, am still reading it.
