Yeah, I could tell there was horror involved - as I wrote back then, the opening scene in the Himalayas was amazing, and seemed to have been written by a totally different writer. But all the (human) characters that followed seemed straight out of a Da Vinci Code knockoff, and I guess I didn't see that changing in the coming pages - that's what ultimately sticks with me about the book. I really hate reading characters like that.* I'd probably watch a movie made from it, but I felt the execution of the concept was too not-to-my-liking to read. I'm sorry :( I think I'll just have to miss out on this one.

*ironically, I can withstand cliched horror characters more easily, so I suspect a lot of this comes down to preference.
