I don't have a good list of books for you right now because I haven't been reading as much as I'd like. I also only have 2 minutes to get this post published, even though I've had it mostly drafted for a month.
BUT - if you are looking for a super absorbing, mystery/thriller with lots of suspense and some excellent plot twists, you will probably want to check out Afterwards. I got it because I enjoyed Lupton's novel Sister quite a bit and this one is EVEN BETTER.
I don't like to describe mysteries too much because I think it ruins the surprise. The voices in this novel are strong, the concept is unusual, the characters are enjoyable and I had a really hard time putting it down during the last 1/3 of the book. To the extent where I was borderline rude to Dustin a few evenings in a row because I was so desperate to get to the ending.
It was a good ending.
