Revenant - Mel Odom

When a Chinese gang hits Sunnydale, racial tensions in the community are sparked. Buffy has seen the baddies shake down Willy the Snitch, so naturally her Slayer senses are up. But to Willow, the situation poses a more personal threat. Her new friend Jia Li has been feeling the backlash from this cross-cultural hostility - and it's tearing her family apart. Jia remains true to her ancient cultural heritage, but her brother, the angry, outspoken Lok, is ready to toss out old Chinese customs for the modern American lifestyle. And he's willing to use the occult for just that purpose.
Suddenly, a beautiful martial-arts warrior arrives on the scene. It's impossible to tell where her allegiance lies, but Xander - whose romances are becoming habitually complicated - is smitten, Giles is in full research mode, and before long, Buffy is wondering who's behind the gang warfare. Is supernatural evil brewing?
