Just finished this book today, quite an excellent read, I had trouble putting it down. I had previous read some of Bruce Blake's short stories and they left me wanting more, Well 'On Unfaithful Wings' was no different, the story moved at a great pace and left me waiting impatiently for the next book. I look forward to getting back into the world of Icarus Fell and seeing where he goes from here. I would recommend this book to anyone who enjoyed 'The Dresden Files' series as I felt it fit in with the same style. If you like urban fantasy, definitely buy this book and read it.
