"For years, the battles between Kin and Transitioner have been inching dangerously close to all-out war. Not the Kin may have just what they need to tip the scales in their favor: Addie Emrys, Evangeline's sister and one of the last remaining descendants of Merlin. If the Kin can get their hands on the Sword of Nuadu and the Stone of Fal, then Addie's help will allow them to break the Eighth Day spell, unleashing chaos upon the world. But Jax won't let this happen. He's Evangeline's vassal, and he'll do anything in his power to protect her and her people. If that means putting everything on the line for a girl he's never even met, then so be it. Addie has other plans, however. No longer in the shadow of her sister and finally allowed to use her magic, she likes how important she is to the Kin, even if she isn't fully aware of their intentions. With the Morrigan on the loose, pushing the adversaries toward total annihilation, Addie has to decide on which side she stands. As the conflict rages and the stakes soar higher than ever, Jax, and Riley, and Evangeline must confront the possibility of losing Addie to save the world." -- Page [4] cover.
