The Opal Cowan series follows a new protagonist in the world of Ixia and Sitia. Opal is a glass artisan who discovers she has the rare ability to trap magic inside her glass creations. Storm Glass (2009), Sea Glass (2009), and Spy Glass (2010) follow her as this power draws dangerous attention.
The trilogy bridges the gap between the original Study series and the later Soulfinders books, expanding the world while telling a standalone story about a character finding her own strength.
