Banished from their small, floating village for forbidden magic, can two sisters work together before the harsh crystalline wilderness kills them-or they kill each other? Elodie-desperate to become the village's next priestess-hopes to atone for their mother's magical destruction, still haunting her family after twenty years. Loxy, her younger sister, wants nothing more than to find their mother, banished long ago for the same magic Loxy now hides. Though they are bound by blood, the sisters live in constant contention, always arguing about Loxy's magic and the danger it poses to their lives in the village. But when a meteor shower full of divine power grants Elodie magic of her own and gives Loxy new power, the two are cast out of their isolated, floating village, just like their mother before them, and into the crystalline wilderness full of dangerous beasts, deadly landscapes, and vicious people. They are destitute and alone when a voice calls to them, one steeped in the very source of their magic... along with a mysterious person who claims they know how to fix everything. With nowhere else to go, Loxy embraces the help and sets out to find the mother she's certain still lives, and Elodie reluctantly follows. But with every step, each sister's hopes for the future deepen the rift between them. When they are finally confronted with the answers to all their questions, the sisters must learn to work together or lose each other-and perhaps their very humanity-forever. Sea of Broken Glass is an adult fantasy starring two LGBT+ sisters and is filled with an exploration of family dynamics, deconstruction, and the restoration of things that are broken.
