At first it sounds like these book reviews might be a little risque, but I feel like I need to clarify because most of the books I read are for children or teens.
Anyway, the last 2 books I've read have come from the adult section of the library. Thought you might be interested to know that I do, in fact, venture out of juvenile literature once in a while.

One Thousand White Women is a historical fiction in that it takes place during a specific time in American history (post civil war, right around the time of the removal of the Native Americans to reservations). It's takes one small piece of real history (the chief of a tribe asks for 1000 white brides to ensure peace) and runs in an entirely fictional direction (what if the president had agreed). Written in a journal style, this was super interesting especially for a girl who grew up loving historical fiction from this time (I'm looking at you, Little House on the Prairie).

Room started off feeling really gimmick-y. It's written from the perspective of a 5 year old boy who was born to a kidnapped teen. His whole life has been contained in the 11 ft by 11 ft shed they are kept in. And while his voice felt contrived at first, I was soon so caught up in the story that I forgot. I also forgot to go to bed at an appropriate time because I couldn't put it down.
