But they're not fighting evil alone. A small, beautiful, but feisty Mexican monster hunter by the name of Xochi rides into the picture on a hot motorcycle. Will Sam and Dean survive working with her? She has her own secrets and comes from a whole different world — at one point the angel Castiel even pops in to say he can't help them. Who knew that there was an agreement between the deities of different pantheons around the world to not interfere with the mortal realms under their power?
Instead of the Christian concept of the hosts of Heaven and Hell holding sway over Mexico, it's the old gods — the Aztec gods like Huehuecoyotl — a god of music, luck, and storytelling. Will the fickle Huehuecoyotl help Xochi and the Winchesters stop the Borderwalker before she kills more innocent people? Will Xochi's family squabbles get in the way? Only time and a few trips back and forth across the Mexican border will tell.
Again, Faust manages to recreate the witty banter, the sarcasm, and the sharp wit of the Supernatural universe for me, making this a fun read. At nearly 350 pages, it went quickly and felt more like an extended episode of the series than anything else. I would have liked to have seen an episode or two made out of this story arc during the season, possibly even a made-for-DVD movie since it easily can stand on its own.
If you like the world of Supernatural and want more adventures with Sam and Dean Winchester, I'd definitely encourage you to pick up Supernatural: Coyote's Kiss by Christa Faust.
