Ever since twelve year old Isabelle Tresdon's silver strand of hair sprouted, it's been nothing but trouble: bleeding pink dust and sparking like a firecracker. Refusing to be known as the girl with the freaky, grandma hair, she wishes it never grew and the hair withers and tarnishes. The only problem is, the strand is Isabelle's source of magic, and she can transform particles of energy into matter. It's also her ticket into Mastermind Academy, a secret school inside the earth's core. Five days remain before the strand drains her magic and life, forcing Isabelle to enter into a deal with two trickster Masterminds to save it. But what she doesn't count on is that there is more at stake than just her life.
