The second English light novel of Sword Art Online is hitting the shelves on August 26th, 2014!! If you are a fan of this series, please consider supporting the author and illustrator (as well as the English publisher)! Pre-orders are currently open on various online bookstores and websites such as:
I highly recommend Barnes & Noble for USA residents and Chapters Indigo for Canadian residents. Book Depository is good for worldwide free shipping. You can also order on Amazon, but know that they are currently having a conflict with Hachette Book Group so… Yeah.
