Wicked Willow I: The Darkening (Buffy the Vampire Slayer) (Buffy the Vampire Slayer (Simon Pulse))

"Willow, what have you done?"
-- Buffy, "Villains"

In the woods outside Sunnydale, Willow Rosenberg has exacted a terrible revenge for the murder of her lover Tara Maclay: She has captured Warren, the murderous leader of the Trio, and flayed him alive. Her best friends, Buffy Summers and Xander Harris, arrived too late to stop her.

But the death of Warren isn't enough for Willow. Now her friends can only watch as the juiced-up witch sets off on a trail of vengeance and magick-gathering to prepare the spell that will bring Tara back to life. And whoever gets in Willow's way is going to regret it...including one Slayer who is still hoping to save her best friend.
