Vampire Slayer, The Vol. 3 [PDF ebook] 

While Xander gets ready for a monstrous confrontation, he finds a new one in his relationship as well… a fight that could mean the end in more ways than one. But Willow and Faith are one step ahead of Xander. Needing supernatural aid, will Willow push herself to a place she may not be able to return from? Despite Giles’ efforts, they may have to live with an irreversible spell. And as Buffy recuperates from the previous battle that’s left her worse for wear, she’ll team up with someone just as reluctant to do so. Can Buffy remember who she was and save Willow from herself… as well as Sunnydale from total destruction? Writer Sarah Gailey (Eat the Rich, Magic For Liars) and artist Hannah Templer (Flung Out of Space) conclude the first year of the WILLOWVERSE storyline! Collects The Vampire Slayer #9-12.
