After everything -- and everyone -- she lost to the Hellmouth, Willow is leaving Sunnydale on a world-spanning road trip in search of her true self. She stumbles on a community of people like her: lost witches looking for answers... but there's a darkness at the heart of it, one that reminds Willow of something she's felt before, something that she fears inside herself. Now, truly alone for the first time in her life, Willow must rely only on her instincts -- and her magic -- to save herself from a threat Buffy never prepared her to face... or the rest of the world will pay the price.
