Welcome to Dim Sum Asylum: a San Francisco where it's a ho-hum kind of case when a cop has to chase down an enchanted two-foot-tall shrine god statue with an impressive Fu Manchu mustache that's running around Chinatown, trolling sex magic and chaos in its wake.

Senior Inspector Roku MacCormick of the Chinatown Arcane Crimes Division faces a pile of challenges far beyond his human-faerie heritage, snarling dragons guarding C-Town's multiple gates, and exploding noodle factories. After a case goes sideways, Roku is saddled with Trent Leonard, a new partner he can't trust, to add to the crime syndicate family he doesn't want and a spell-casting serial killer he desperately needs to find.

While Roku would rather stay home with Bob the Cat and whiskey himself to sleep, he puts on his badge and gun every day, determined to serve and protect the city he loves. When Chinatown's dark mystical underworld makes his life hell and the case turns deadly, Trent guards Roku's back and, if Trent can be believed, his heart... even if from what Roku can see, Trent is as dangerous as the monsters and criminals they're sworn to bring down.
