Template:Article Angel: The Hollower is a trade paperback collecting comic stories based on the Buffy television series.
Angel has an encounter with someone from his past, and now has to face a threat he had hoped had been long destroyed: the Hollower. The Hollower is a natural predator of vampires. The hideous thing might be linked to Angel's salvation or his destruction.
Buffy comics such as this one are not usually considered by fans as canonical. Some fans consider them stories from the imaginations of authors and artists, while other fans consider them as taking place in an alternative fictional reality. However unlike fan fiction, overviews summarising their story, written early in the writing process, were 'approved' by both Fox and Joss Whedon (or his office), and the books were therefore later published as officially Buffy merchandise.
