I'm reading To Sleep in a Sea of Stars by Christopher Paolini. It is a lot of fun so far. The characters are deep and believable. The plot is complex and interesting. I love it!
I just finished Whalefall by Daniel Kraus if you are looking for a gripping, hard-science, scuba survival thriller. The ending is so metal. The writing is great and the tension makes it hard to read and hard to put down.
