Okay, quoting myself here. At 280ish pages, this felt like a pipsqueak of a novel. Breezed through it in two nights. FWIW, it looks like this is a new beginning of a series. I would have been fine if it was a standalone. But this book just revved me up for wanting more!
I just finished it, too. It was a very fun read, and it was nice to see how he incorporated the people and events from the first series into the more "modern" world.
Sanderson said he originally pitched Mistborn as a set of 3 trilogies: Fantasy, Urban Fantasy, and Science Fiction. This one was more of a one-shot between the first and second trilogies, but he may continue the adventures in this era in a follow-up book. If he doesn't, he said we'd get resolution in the Urban Fantasy trilogy.
