Mona Lisas and Little White Lies by John Herrick

After a chance encounter when Ryder, a starving artist, rescues a drunk Lily at her cousin's wedding, he can't get her face out of his mind. She becomes his muse in everything from his own personal paintings to magazine and billboard advertisements.
Lily, an auto mechanic, has become a celebrity without even knowing it and everyone is clamoring to find out who the woman in the paintings really is. When she finds out, she tracks Ryder down to confront him but ends up falling in love with him. She only wants to be the glamorous woman he's created on canvas. One little white lie about her job won't hurt. But when the truth hits the tabloids, everything falls apart.
I thought this was a different twist on the Cinderella story. Like the Prince in the fairy tale only having a shoe to find his true love, Ryder has only a first name and the memory of her face. Cute story.
