Orphan. Thief. Witch. Twelve-year-old Quicksilver lives as a thief in the sleepy town of Willow-on-the-River. Her only companions are her faithful dog and partner in crime, Fox - and Sly Boots, the shy boy who lets her live in his attic when it's too cold to sleep on the rooftops. It's a lonesome life, but Quicksilver is used to being alone. When you are alone, no one can hurt you. No one can abandon you. Then one day Quicksilver discovers that she can perform magic. Real magic.
