Knight of Ghosts and Shadows

Elves in L.A.? It would explain a lot, wouldn't it?

In fact, half a millennium ago, when the elves were driven from Europe they came to – where else? Southern California. Happy at first, they fell on hard times after one of their number tried to force the rest ot be his vassals. Now it's up to one poor human to save them if he can. A knight in shining armor he's not, but he's their last hope.
