The Price of Folly — Denise Robins

All because of twenty-four hours in Paris, and an innocent mistake. Rich, handsome, sophisticated Alan Rivers sweeps Paula off her feet. His charming declarations of love and his fervent promises of marriage throw her into a sweet delirium of unreasoning bliss. But when she realises Alan's affections are as false as his promises, and her own feelings are mere infatuation, she soon comes to her senses. But will it be soon enough to salvage a future with a man who really matters? Can she free herself from the schemes of the vengeful Alan? An innocent indiscretion threatens a young girl's chance for happiness and love!
