The Glass Books in Order

The Glass series steps sideways from the early Study books to follow glass magician Opal Cowan as she learns just how dangerous her art can be.

When Storm Glass opens, Opal is a young glassworker in Sitia who once played a small role in Yelena’s story and would prefer to fade back into the background. Her ability to channel magic through glass makes that impossible. Stormdancers, magicians who ride out tempests and trap their energy in glass orbs, are seeing their orbs shatter and their strongest members die, and Opal is the one person who might be able to find out why. Drawn into an investigation that stretches from quiet studios to deadly storms, she has to test the limits of powers she barely understands.

In Sea Glass, Opal is no longer anonymous. The glass messengers she has designed can carry communication across huge distances, and every power in Sitia wants a hand on that network. At the same time she is chasing proof that outlawed blood magic has not gone away, putting her at odds with the Council, her mentor, and even her family. The book leans into questions of control, who owns a tool once it changes the world, and whether Opal can hold onto her independence when so many people see her as a resource to be used.

Spy Glass picks up after a devastating choice. To stop a villain, Opal has stripped herself of her magic and discovered that she is now immune to other spells as well. That loss leaves her on the outside of the magician community she used to belong to, but it also opens the door to a new role, spy and saboteur, using her immunity and her glasswork to expose plots that threaten Sitia and the people she loves. As she hunts those who have stolen her blood for their own schemes, she has to decide what kind of power she truly wants, magical, political, or something quieter but just as strong.

The companion novella Shattered Glass continues Opal’s arc after the main trilogy. While she is trying to teach her adopted daughter Reema how to work molten glass, a troubling letter arrives from her former mentor, Master Magician Zitora Cowan, who vanished while searching for her missing sister. Opal, wary but loyal, travels with soldiers Nic and Eve to a remote clan town to find out whether the call for help is real or a trap, and the story offers a tighter, more intimate adventure that still carries the emotional weight of the larger series.

Across all of these stories, expect a mix of magic, mystery, and slow growth as Opal moves from insecure apprentice to a woman who can decide for herself how she wants to use her gifts.
