I'm a big fan of Powers, for the most part; the Fault Lines
books are on my "Favorites" shelf for a reason. I missed this one when it was first published and thought I might enjoy a second spin with an old favorite author, but I was a little disappointed. The first hundred pages were a bit more disjointed than I'd like, and some of the characters seemed a bit stiff and overused (the chain-smoking Shakespeare-quoting English professor, to wit.) The pace was good, though, and the word "thriller" definitely fits. It has real grit in places that some more contemporary supernatural thrillers don't.
I enjoyed the book, and it was a page-turner for sure, but it doesn't have quite the depth and surprise of Earthquake Weather
or Last Call.
I'd recommend it, but only with a few reservations.
