Award-winning author Maria V. Snyder brings readers into a world of molten magic, where storms can be captured within a glass orb and a magician's powers can remain hidden...until challenged by enemy forces.

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. Yet the further she delves into the intrigue behind the glass and magic, the more distorted things appear. 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.
