I've just finished a YA book called Vivian Versus the Apocalypse. It was one of those which I ordered, then decided I wasn't sure about it. I picked it up, and ended up really liking it. America is in the grips of The Church of America, a sinister cult which has predicted The Rapture. When people actually do disappear, including Vivian's parent's, she sets off to try to find some answers.
There is a romance, but it's a gentle one, which is just a small part of the story, and Vivian's friendship with Harp is shown as more important - which was refreshing in YA.
Audio is Allegiant - I am really loving being back in the Divergent world, but there's a lot to take in, and at the midway mark I'm a little disappointed in the way it seems to be going, but I really want to see how she wraps it all up.
