The Veil - Ivy Brannon - Bog

The veil was supposed to be myth.
Legend says it separates the human world from one full of monsters and magic, and every year on the holiday of Samhain, it lifts. That night, anyone... or anything... can pass between the two. But it's only a legend, of course.
Or so Lina Calder thought.
Then her brother is stolen away in the night, claimed as a Changeling, and legend becomes horrifying reality as Lina's search thrusts her into a treacherous new realm. There she is forced to ally with a powerful Fae king, but despite his favor, Lina's presence still makes waves. Dark creatures clamor for her blood, a war between good and evil inches closer by the day, and her brother's whereabouts remain a mystery. As Lina attempts to find her place in a world hellbent on seeing her dead, her journey leads her to the farthest reaches of the realm, testing her courage, her heart, and her will to survive along the way.
