A Winter Wish by Megan Ryder

Mirror Mirror on the wall, show me my true love.
Callie Ricci, research librarian and self-avowed romantic, has been waiting her whole life for her prince to come. She saw him for the first time when she was eighteen in a magic mirror, but his face was obscured. Every midwinter she gets a glimpse of him, but each year the figure moves slowly away, indicating the love is fading, become less of a possibility.
Alexander Morin, local police officer and protector, has always been in love with Callie but she has never seen him as anything other than a friend. Convinced he’s lost his shot, he resolves to find a new job and life elsewhere.
When someone tries to steal the mirror, Alex and Callie must take the mirror into hiding for safekeeping. As they spend time together, they may discover more than a thief. They may discover true love.
