Great storyline! It's like epic fantasy thrown into a hot vat of Victorian England, and served alongside rolls of page-flipping enthusiasm!
The plot is quite unique. I think it's a bit 'sci-fi' in nature though... The plot is also 'character-geared'. It tends to focus more on the development of the individual characters in place of the rest of the happenings in the story. The characters are brilliant.
While the high GR rating this book has from me is largely as a result of the extraordinary ending, it will continue to have extraordinary stories in subsequent books in the series. I look forward to book 2
