In Pieces on the Ground — Joss Whedon

Demon invasions wreak havoc worldwide when an interdimensional portal lands in the wrong hands--those of the Mistress, the Sculptor, and the Soul Glutton. As new threats pour into the streets, Buffy and her closest allies find their paths diverging: Willow gets a serious job, Xander and Ghost Anya grow perilously close, Andrew is tempted by evil, and Buffy and Spike continue to work at making their relationship, well, work. And as the real and supernatural worlds collide, Dawn is forced to make a life-altering decision.
