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.
