Ever since the untimely death of their parents, Anne, Beatrix, and Violet Quigley have made a business of threading together the stories that rest in the swirls of ginger, cloves, and cardamom at the bottom of their customers' cups. Their days at the teashop are filled with talk of butterflies and good fortune intertwined with the sound of cinnamon shortbread being snapped by laced fingers.

That is, until the Council of Witches comes calling with news that the city Diviner has lost her powers, and the sisters suddenly find themselves being pulled in different directions. As Anne's magic begins to develop beyond that of her sisters', Beatrix's writing attracts the attention of a publisher, and Violet is enchanted by the song of the circus--and perhaps a mischievous trapeze artist threatening to sweep her off her feet. It seems a family curse that threatens to separate the sisters is taking effect.

With dwindling time to rewrite their future and help three other witches challenge their own destinies, the Quigleys set out to bargain with Fate. But in focusing so closely on saving each other, will they lose sight of themselves?
