Shakedown (Angel novel)
Shakedown is an original novel based on the U.S. television series "Angel". Plot summary. Doyle has a vision of a seismic shift, and everyone's guard goes up. After investigation, Angel is led to a group of Serpentine demons who live locally in a wealthy and private community. Despite close associations with telemarketing, this group of 'monsters' seems harmless and has no enemies, yet it has become the target of a clan of underground quake demons. The quake demons can reduce living things to a crushed mess. Cordy and Doyle are dubious of their new clients, but  Angel soon finds out he has much in common with this community. Continuity. Canonical issues. "Angel" books 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"/"Angel" merchandise.
