This is a strange book for me to review because I am not a fan of steampunk or urban fantasy, and this was definitely an urban fantasy steampunk book, full of zeppelins and men in overcoats and elves in London and a murdered vampire. Despite being predisposed to not like it, I really enjoyed it. It's essentially one big chase, as our Library agent heroine goes into an alternate world to retrieve a valuable book, only to get mixed up in an elaborate plot loaded with skullduggery and cyborg alligators. Lighthearted and fun.
