As a glassmaker and a magician-in-training, Opal Cowan understands trial by fire. Someone has sabotaged the Stormdancer clan's glass orbs, killing their most powerful magicians. The Stormdancers--particularly the mysterious and mercurial Kade--require Opal's unique talents to prevent it from happening again.

But when the mission goes awry, Opal must tap into a new kind of magic. As she delves into the intrigue behind the mysterious glass orbs, she uncovers secrets not even she could anticipate. With lives hanging in the balance--including her own--Opal must control her powers...powers that could lead to disaster beyond anything she's ever known.
