Witch & Wizard

From Yen Press:

Imagine waking up to find that the world around you — life as you know it — has changed in an instant. Whit Allgood and his sister, Wisty, are just your average teenagers — until they are rudely awakened one morning by helicopters on their lawn and a unit of armed policemen hauling them out of bed. Accused of holding incredible powers they’d never dreamed possible, Whit and Wisty are shocked to find that their alleged “dangerous” magical powers are very real. And now, just how different they are — special, even — is just beginning to come to light as they and other young people rise up against the tyranny of the New Order.
