This is the final book in that trilogy. Oh, and if you didn't get any of those in-jokes in the first paragraph, then go away, and don't come back until you've read all of them. They're good. It's worth it. **And there are serious spoilers from here on out.**
Here we go: The Hero of Ages.
Years ago, Vin killed the Lord Ruler, ending his thousand-year reign. But it turns out that might not have been the best idea. Now the Deepness has returned in the form of lethal mists, alongside powerful earthquakes and heavy ashfalls. She and her husband, Elend Venture, now a Mistborn after the events at the Well of Ascension, must travel all over the empire to find clues the Lord Ruler left behind. Maybe these will show a way to defeat Ruin, the force Vin freed at the Well. Ruin is out to do as he promised he would, long ago: bring about the end of the world. And Vin can't talk about it with anyone, or else Ruin will find out her plans.
Now, this book is filled with drama. There are revelations everywhere that make you go, "Oh, wow, of course!" I can't really describe how good it is. This is what fantasy is meant to be. All of the glowing praises I lais on the first two books still stand, but multiplied tenfold. Simply put, Mistborn is not a reading experience to be missed. I purposefully haven't outlined much of the plot so you will be just as surprised as I was reading it. Don't miss it. It has given me complete faith in Brandon Sanderson to finish A Memory of Light, the last book in Robert Jordan's Wheel of Time saga. Now I need to go find Elantris somewhere...
My rating: 10/10. Read it.
