A Bond of Broken Glass by T.A. Lawrence

The shoe fits, but she’s no Cinderella.
Ellie knows what she wants in life:
Open a glassblowing shop in the art district.
See her father retire.
Marry for love. (If she can find someone who can keep up, that is).
Winning the fae prince’s heart doesn’t make the list.
So when Prince Evander throws a ball to find a human bride, Ellie respectfully declines. And when she reads the morning paper and discovers the prince danced the night away with a mysterious stranger, only for the woman to flee at the stroke of midnight, Ellie can’t help but laugh.
Until she learns the mystery girl left behind a glass slipper.
Ellie’s glass slipper. From the set that went missing from Ellie’s workshop.
So when the idiotic prince decides it’s a good idea to use the slipper to identify the love of his life (because, you know, no two women could possibly share the same shoe size), Ellie doesn’t hesitate to prove the slipper is hers.
Little does she know there’s been a modification to her work of art. The prince may or may not have attached a fae bargain to the shoe, and when Ellie places it on her foot, she finds herself both legally and magically betrothed to the very prince she detests.
Not that Prince Evander is thrilled about the situation, either. After all, he’d thought the shoe would only fit Cinderella.
Together, the unhappy couple must discover a way to break the fae bond, but there’s danger along the way.
And what’s more dangerous than falling in love with someone whose heart belongs to another?
