Witch & Wizard: The Manga, Vol. 1

Imagine you wake up and the world around you-life as you know it-has
changed in an instant. That's what has happened to Whit Allgood and his
sister, Whisty. They went to sleep as normal teenagers, and woke up as
wanted criminals. Accused of holding incredible powers they'd never
dreamed possible. And now, just how different they are-special, even-if
just beginning to be revealed in a strange new world.
