Fear's Mirror — Michele Lang

Viv Levy, owner of the Sacred Circle magic store in New York City, knows she runs a big risk in her job. All kinds of supernatural currents, including quite dangerous ones, run under, through and above the streets where regular people walk. And evil often seeks a place of power...
A mysterious stranger seeks Viv's help in dealing with a sinister magic mirror, and another stranger arrives when all appears lost. But will Viv herself have the courage to look into Fear's Mirror?
An urban fantasy short story set in the world of Michele Lang's Ms. Pendragon series!

“This is simply a fantastic read....Ms. Pendragon has the best Arthur and Guinevere I have seen in years of reading everything I can find about Camelot. Merlin is completely charming, and not since Mary Stewart has Mordred received a better treatment.” �" Amanda Killgore, Huntress Reviews (review of Ms. Pendragon)
