'The Lilac Girl' is a romance novel written by Ralph Henry Barbour. Wade Herrick, the main character of the story, was taking a break with his business partner in a train station at Colorado when he fell in love at first sight with a female passenger, Eve, who was disembarking from a train. Enamored, he confessed his love for her, and she, amused by his pluck, gave a sprig of lilac in appreciation before leaving. Fast forward to five years later, and Wade found that Eve is now his new neighbor — does she remember him and will Wade be able to win her over this time?
