Favorite books of 2015?

I'm interested in finding some good reads and thought to get your favorites. I generally read horror as my favorite books were

Finders Keepers

Bazaar of bad dreams - both by Stephen King.

I didn't really read much more new fiction this year, kind of just reread the Stand and On Writing by King.

Edit I thought Armada looked good if anyone read it?

I don't read books.I only read magazines.Reading books for me does not register in my head for some reason?

Uhhhh most of the books from this year I've read are non-fiction.

America's Bitter Pill: Money, Politics, Backroom Deals, and the Fight to Fix Our Broken Healthcare System by Steven Brill
The Billion-Dollar Spy by David E. Hoffman
Red Notice: A True Story of High Finance, Murder, and One Man’s Fight for Justice by Bill Browder
The Nightingale by Kristin Hannah

Really didn't read a whole lot besides textbooks. I checked out Killing Patton from the library cause I didn't want to give Bill O Reilly any money and after a few chapters of military history, I couldn't take anymore. Was hoping it was going to be a more personalized look at Patton off the field but I guess not.
