Hidden Away is by far the book that made an absolute mess of my head. The amount of crying I did was astounding. This is not an easy read, you are reminded of the atrocities that were done by the Nazi's, while witnessing such amazing love. Heartbreaking.
Aristotle and Dante Discover the Secrets of the Universe is such a beautiful story. The writing is so exquisite and purposeful that you can't help but be swept into this story. Even if you do not read young adult, you might want to take a chance with this amazing read.
Captive Prince Volume Two...WOW! My absolute favorite read, I've read it over a gazillion times. Even just thinking about it now makes me want to read it again. This is such a well thought world, with intense political maneuvering, and enemies to lovers with so much tension. Absolutely brilliant!
Obviously, my can't wait for read in 2014 is Captive Prince Volume Three :D
