Calamity, by Brandon Sanderson
The second review:
I read this while I was waiting in line for Naomi Novik's signing. It was a fast read because it isn't long.
Calamity is the third book in a series. The sampler makes it clear the setting is someplace you won't understand unless you read the whole book, or the ones that came before it. That doesn't suck you in. You don't get a sense of each character and since I couldn't relate to the setting I didn't want to read more of this book, much less the first two.
Since it says "San Diego Comic-Con 2015 Exclusive" on the cover, I wonder if I can sell it on E-Bay.
