Anyone reading The Traveler?

I just got it as a gift. I’m onlu on page nine, so I have no opinion yet, although, it does seem rather dark and unrelenting.
Any insights, comments, or warnings?

I enjoyed it. It was well-written and interesting, in a conspiracy-theory sorta way. I had no idea that it was the first in a trilogy (?) so I was disappointed when it didn’t end. I would never have bought it had I known, since I don’t like having to wait for endings. The techno-science in it is BS, but that isn’t unusual in these types of books.
