Under Wicked Sky - Under Wicked Sky, #1

The apocalypse has arrived. And it has feathers. On the afternoon of April 22nd, magic returns and sweeps across the globe, bringing terror in its wake. Everyone over the age of seventeen mutates into a terrifying bird-like creature, and they're all hungry for human flesh. By evening, children are all that remains of the human race. Clarissa and her friend Dylan are two of them. Dylan's South Lake Tahoe home is isolated enough to survive the worst of the chaos, but wildfire, dwindling food supplies, and starving predators encroach on their island of safety.
Worse, when Clarissa is bitten while defending her little brother, a spray of feathers grows from the damaged flesh and all she can stand to eat is meat. The rawer the better. Dylan receives visions which hint at answers and possibly a cure in a distant seaside town. But with the monster inside Clarissa singing a siren song of blood and violence, she must fight to keep her humanity long enough to make it there.
