The Golden Age of Magic by Luanne G. Smith

Against the backdrop of 1920s Hollywood, a young fairy godmother on a mission is embroiled in malicious magic, mystery, and murder in a thrilling historical fantasy by the bestselling author of The Vine Witch.

Celeste is about to become one of the thirteen Fees Gardiennes, a centuries-old sisterhood of fairy godmothers. To be granted full status, she must usher her first protege onto their path of destiny. Where better to find a starry-eyed ward than in the land of magic and illusion called Hollywood?

It's 1927. The moviemaking business is booming when Celeste befriends a young studio seamstress whose dreams outshine everyone else's. Rose is talented and underappreciated and could use some enchanted intervention in her life. Plans proceed swimmingly, and Celeste even catches the eye of a handsome producer. But after a series of unexplained accidents on the studio lot stir up rumors of a curse, Celeste fears the trouble is more personal-the spiteful meddling of a fellow Gardienne out to thwart Celeste's success.

But the sabotage turns sinister when a starlet is murdered and it's Rose who stands accused. As vengeance, dark magic, and betrayal wreak havoc, Celeste must come into her full power to save her innocent protege and secure her own future in a cherished, ancient, and now threatened sisterhood.
