One Dark Destiny

Rosalie, the beautiful poisoner, rumoured the strongest healer in all of Prynn.
Ariadne, the mystical Oracle, who is said to have the ability to read minds.
Calliope, the enchanting Elemental, as cold hearted as her frozen gift.

Hundreds of years before the birth of Mirabella, Arsinoe and Katharine, was the birth of these three sisters. In a time where the Island of Fennbirn was a very different place, the three Queens are fighting for much more than the throne. Sister killing sister... that's just the way it has always been... right? But the past and the future have started to collide and suddenly the Queens are not just fighting each other. A greater threat looms over the island, and things are not the way they should be. The sisters must grapple with fate and hope and the power to change history. Every rebellion has roots, even if they take hundreds of years to blossom. This is a story about the events that enabled Jules Milone's rebellion, and about three sisters questioning whether you really can fight destiny.
