The Book of Kell

Warning: homophobic slurs. I don't know of any other because I didn't read further.
I think I could've liked this book a lot, but I just ended up not being interested in it. And I got about 30% in and realised I wasn't enjoying it.
I liked the premise – the post-apocalyptic plot, the characters have to travel. But that wasn't enough to keep me reading.
