Buffy The Vampire Slayer, season 8, book 38: Last Gleaming, part 3
Joss Whedon et Georges Jeanty2010

While Super Buffy is fighting side by side with Spike in Sunnydale, Angel is on the other side of the world fighting demons of his own. As Twilight he was given a clear mission in regard to Buffy--help her reach the next plane, together create a new world, and end all suffering. But Buffy doesn't play by the rules, and this "higher plane" and a lifetime of happiness with Angel wasn't gonna cut it--not if she had to sacrifice her family to keep it. And now Angel has to answer for his failings as Twilight--willingly or not.

Back in Sunnydale everyone is fighting for their lives against a horde of demons, and someone close to Buffy joins forces with a villain from the past to strive for a common goal--protect the seed.
