Shamelessly reusing my Amazon review:
A thoroughly enjoyable read. The language and dialogue is believable and a great deal more realistic than a lot of contemporary fantasy novels, which tend to be overly 'nice', the storyline is engaging and I honestly didn't want to put it down.
Redoubt is exactly what you would expect of a good fantasy novel, it touches on the variety of races which, hopefully, we'll see more of in later books, it has magic, warfare, well developed characters and plenty of scope for sequels. If you are a fan of David Gemmell, or just fantasy in general, I definitely recommend it and if you are looking for a new Author whose writing is engaging, enjoyable and easy to read I heartily recommend Alexander Janaway.
(When you've finished this one, I heartily recommend "The Coming of Night" too)
