The Halo series has an expanded universe chock-full of exciting stories, intriguing lore, and memorable characters. Ever since the first book was published back in 2001, Halo's book portfolio has swollen to almost 30 complete novels, as well as several comic books, graphic novels, and in-depth encyclopedias. Here's what we think are the best nine Halo books you can buy right now.

Overall, every single book on this list is a fantastic read. However, if I had to recommend one, it would be Halo: Broken Circle since the Covenant is my favorite part of Halo. Fans of the human side of the universe will get a real kick out of Halo: The Fall of Reach, while people who like all of Halo will likely enjoy Halo: Evolutions the most.
