Morgan in the Mirror — A.L. Tyler

Sixteen-year-old Penny Sparks needed a job and a knight in shining armor. She didn't expect to get both of them quite so literally. Now working the summer at Dragon's Brackens renaissance festival and enjoying a flirtation with one of the dazzlingly handsome show jousters, she thought her life had become exciting enough. She's about to walk in on her boss, a humble mirror artist, doing something not quite normal. Not quite human, even. Because as it turns out, the owner of Morgan's Mirrors is a Fay... Morgan le Fay. And with her cover blown, she's now demanding Penny's help hiding from an evil wizard and a secret order of knights that have hunted her through the ages. She's willing to compensate Penny for her time with magic. Even so, what she's asking is way above Penny's pay grade.
