This book, like its predecessor Storm Crow, is superbly written. Even for a longish novel, Jeff Gulvin keps the plot moving at a fair pace and his attention to detail throughout is admirable. These qualities and the very strong storyline combine to make this a "100 page a night book" which has kept me awake until the early hours.
The only criticism I would make is that, for me at least, the book seemed to end too quickly. It is some 570 pages long, but seems to come to a pretty hasty and and in somes ways unsatisfactory ending in the last 20 pages. The great detail which is present in the first 28 chapters disappears in the last 2 and this left me feeling very slightly "short changed".
