There are many stories that involve modern military timeslipping into our past and over-whelming some blade wielding foe and this is a good example of the genre.
Never before considered the Australian SAS, but the description of the men and their actions all seemed plausible. The characters were pretty well developed and the story sets off at a fair pace. The whole mission into Iraq seemed accurate and was itself gripping.
Then the drop through time and space. I found I struggled with the early part of the "SAS meets the Danes" section. There were all sorts of issues for the reader to overcome - the ease at which all the farmers adopted English was something that just had to be tolerated for the sake of the story. But I also was unconfortable with the way the soldiers behaved. They didn't survey the village for long, they split up and billeted all over the village, didn't really protect their gear......the list goes on.
Once you park this lot, you can get back to enjoying the story. Some of the actions were predictable (defeating the raiders - hooray! This is the sort of thing we started the book in the first place for). There were plenty of unexpected plot twists, loads of action, a good romp across tribal Europe and a satisfying ending. What more can you ask for. More? Certainly!
I got it for free, but would happily have paid for it. Will look out for more from this author.
