Just finished City of Blades by Robert Jackson Bennett, hands down the best book I've read this year. I didn't think an adequate follow up to City of Stairs could exist but this surpassed every expectation. If you're looking for a gritty, nail biter of a fantasy novel I highly recommend you give this series a shot. This guy writes like a freight train, it may take some time to gain momentum but when it picks up you can't help being swept away.
