I enjoyed the first book, The Dig, because it was a very novel idea to have someone experiencing the past by touching an artefact, although there were a few holes in the plot, but neve mind. The back story about an ancient African civilisation was interesting, compelling and coherent, and suitably embedded into the "now" story.
In this second book, the back story is disjoined and incoherent, and in some parts I couldn't make sense of it because it jumped times too often. Egypt, Damascus, Norway, Iceland, Cuba?
Unfortunately both the "back" and the "now" story are full of crazy violence, beating, killing, torturing, shooting, injuring and you name it, to the point that I got sick of it. I lost track of all the involved parties and how they all ended up in the same place, killing each other or just about limping through on multiple injuries. I wanted the book to end. I would have abandoned it if I hadn't already made it two thirds into it. Disgusted. No more Matt Turner for me.
