The Covenant of Roses

Every citizen of England can make a bargain with the immortal fairy queen.
High-society girls usually make bargains for specific traits that will secure them husbands: a rare talent on the piano in exchange for someone's happiest childhood memory. A perfect smile in exchange for the sense of taste.
But the season of Ivy's debut arrives with a shocking twist. The queen announces a competition… and the winner will marry her son. If she wins this prize, Ivy will be able to save her family and free her older sister from the bargain that ruined her.
However, behind the fairy bargains, the fancy balls, and the shimmering dresses lies a dangerous alliance that could overturn everything.
