Yet another of the books I've read on Saturday mornings in Waterstones. And for that purpose, its fine: undemanding, fun. Read all about it: Daughter of smoke and bone.
But - and its the usual but - it is ultimately forgettable, derivative, formulaic. Perhaps its the book someone who would have liked to be a 17 year old art student in Prague would have written. The initial ideas and environment sits well, the odd situation is nicely set up, but as so often it falls down in trying to make sense of the initial setup (if three's a war over there, and one side has doors into here, then why mess around with teeth? Buy guns! And so on).
And yet, if part two appears and is any good, I'll likely read that too.
