A Waltz Before Midnight — Juli D. Revezzo

When Cindaria Hethrope and Mr. Spencer Moreland collide, the collision destroys a precious gift for her ailing sister. Her nasty stepmother won't purchase another, so Cindaria has no choice. She must agree when Spencer offers to procure it for her, even if it means traveling outside London with him to meet the creator. All Spencer wants is to clear his debt to the infuriating Cindaria, and forget the horrid, no good day he had less grace than an earl's son should have. Then maybe he can put this girl behind him and find the charming beauty who stole his heart at a recent masked society ball. If only he had a glass slipper to prove what his heart tells him is true...
