Hignett, Lauretta. Welcome to midlife magic #1

"Starting over isn't easy when your whole world is a pile of rubble and everyone thinks you're insane. One moment, Susan Moore had the perfect life--a handsome husband, a fabulous career, wonderful friends, and a gorgeous home in Pacific Heights, San Francisco. The next minute, it was all gone. And Susan found herself in a straitjacket, locked in a padded room. An optimist at heart, Susan's clawing her way back, rebuilding her life brick by brick--not an easy feat when you're over the hill and it feels like the whole city hates you. But when a group of ridiculously gorgeous models in Fae cosplay barge into her tiny apartment and declare her to be the chosen one, Susan decides to play along. She's off to save the world. Except they're not in cosplay. Either Susan has really, truly gone insane this time... or all this magic is real."--Amazon.com
