Quite good, but Im not too keen on the hero being a captain cave-man, which he kind of was. It was quite an intersting storyline though and there were a couple of characters I would have liked to get to know more. There was a lot of sex in there too!
I felt the ending was a bit rushed and that there were some loose ends that I thought they were going to make more of, such as what Emily was and perhaps more about Niol. But maybe these are for future stories...?
