An interesting and absorbing tale let down, as previous reviews mention, by a shocking amount of spelling & grammatical errors. I almost stopped reading because of this. Also, there are some scenarios that simply beggar belief, and I don't mean the supernatural elements. For example, could a teenaged student really leave home to return 6 short years later as a seasoned and outstanding SAS officer?! However, despite some unnecessary filling (a brief history of popyrus, and of blood groups), this is quite a good, fun read. Some of the twists I figured out quite early on and, by the author's own admission, the central storyline isn't original. That said, the historical elements are well researched and the action sequences are well executed. Given the author's background in teaching, I don't believe the obvious, glaring errors are his. Therefore, I'd say that this is a pretty good first novel. Good enough for me to give his second novel (the start of which is included) a read before giving up on this author. Three stars because it's a four star story but a one star editing/proof reading/publishing job.
