The Strength of a Heart — Ioana Visan

One day, a pair of wings will change the world. Alise's wings are killing her. Twice condemned to death, Alise is slowly fading away after a poisonous Mermaid's bite, but Rafe will have none of that. Along with two other Guardians of Balance and Alise's human friend, they go in search of a cure in The Mists, where Gorem's Wizard is in hiding. Their journey will be met with danger and strife along the way. With werewolves, demons, dangerous sea creatures, and Alise's poisoned-filled wings growing back, their chance of survival is slim. Will Alise survive another murderous plot?
