Firstly, let me say that no Wilbur Smith book set in Egypt will ever deserve less than a 5 star rating. In spite of this, The Seventh Scroll is just a tad below River God and Warlock, but it is still a great read.
One thing to note about The Seventh Scroll is the choice of characters to lead, Dr. Royan al Simma and Sir Nicholas Quenton-Harper. In keeping with Wilbur's style from River God, these characters are introduced very early on which results in their traits being described very fully. A good thing, because it allows for the plot to continue without restrictions, and at its fast pace.
Sir Nicholas has many things in common with River God's hero, Tanus as they are both heavily reliable warriors of their time but, unlike Tanus, Sir Nicholas is not infallible. On the other hand, Royan is extremely likeable for her intelligence and mannerisms, but is still a lot unlike any of the female characters from either River God or Warlock. I was relieved to note that Wilbur had decided not to recycle his character traits, unlike many other authors. I particularly enjoyed reading about Royan!
Overall, this is a book that will entice you into reading it. In my own personal experience, I had no intention of beginning it when I first picked it up at 4am some morning- but I ended up reading 15 pages. Similarly, I read 200 pages in just under two hours a few nights ago to finish it at 7am because I just had to know what would happen!
My only complaint is that Wilbur Smith has found his niche in these Egyptian novels (Sunbird, River God, The Seventh Scroll, Warlock) but he does not seem inclined to add any more titles to the list. It is a shame. These are clearly my favourite books.
