Bonded by Desire by Elly Osenton

Surviving in the pits of Alexandria closed Avalaine's heart and put a sword in her hand. She'll risk her life to save those who deserve it and be the retribution in the shadows for those who don't. Avalaine's life is thrown into chaos when her world collides with Humphrey - an exiled fae warrior sent to kidnap her.

The Great War eradicated the immortals from the city of Alexandria. The commander of the fae army banished by the witches for his tyranny and his army cursed. Hundreds of years later, the mortals suffer in a torrid winter, on the brink of starvation.

Avalaine has always protected her sister from their abusive, drunken father... but in doing so, triggers a chain of events that will throw her life into chaos. Kidnapped by a fae warrior and taken to a city ruled by a powerful sorcerer, Avalaine must confront her forgotten heritage, navigate power-hungry celestials, and vengeful fae warriors in a world where survival demands sacrifice.

Forced to abandon her life, Avalaine is pulled into a brutal world of magic and curses for the promise of limitless power. To survive, she must trust the wicked sorcerer who has bound her fate to a dark protector she cannot escape.

In a world built on betrayal, lies and forgotten power, Avalaine must put her trust into those who have yet to earn it.
