Number 6 is The Well of Ascension by Brandon Sanderson.
The second book of his Mistborn series and whooboy I did not like this book at all. I started it just after Christmas, and gave up on it for awhile. But as I have a real hard time leaving a book behind, I persevered. But I realized pretty quickly in that I do not like Vin as a character at all. I don't find her interesting nor engaging. The same with Elend. And their melodramatic relationship just made me go 'ugh, please just breakup' (and I'm not one who is easily bothered by silly, young relationship drama). Some of the stuff with Sazed would've been interesting, and I wanted to see what happened to Marsh and got him to where he would be at the end, but nope. And the ending just came across as such a big mess that I don't care what happens next. I won't be continuing on in this series.
