Only an okay read, and for me I think the biggest issue was the prose. This was written in the 80s, writing prose has changed since then, and the style from back then I personally find harder to get through. Lot of description, even if it's just the set up of a room.

Plot wise, this was okay. I guessed early what was going to happen, a twist made me reevaluate that, and then things settled into my original guess. The main character Doyle, was also a little too passive for my taste. Though that might also be because the villains began to see him as a formidable foe even though he wasn't anything special.

There were elements I enjoyed a lot: double time travel, an interesting limitation to magic, the use of Egyptian mythology. I just guess, since I have heard so much about this book, I expected to like it better than I did. But isn't that how it typically goes?
