A TIME Magazine Top 10 Children's Book of 2015

"The Trilogy of Two is full of inventiveness, with a world that's constructed ingeniously and characters who are vivid and attractive."--Philip Pullman, author of His Dark Materials

Identical twins Sonja and Charlotte are musical prodigies with extraordinary powers. Born on All-Hallows-Eve, the girls could play music before they could walk. They were found one night by Tatty, the Tattooed Lady of the circus, in a pail on her doorstep with only a note and a heart-shaped locket. They've been with Tatty ever since, roaming the Outskirts in the circus caravans, moving from place to place.

But lately, curious things have started to happen when they play their instruments. During one of their performances, the girls accidentally levitate their entire audience, drawing too much unwanted attention. Soon, ominous Enforcers come after them, and Charlotte and Sonja must embark on a perilous journey through enchanted lands in hopes of unlocking the secrets of their mysterious past.
