This Sword Art Online eBooks are from fans translation. So far I have only read the Phantom Bullet saga and the translation should be ok — I mean, it is not that horrible. The eBooks are in MOBI format (compatible with Kindle). Credits to the original uploaders and translation teams (I’ll try to update later).
