Light from Uncommon Stars by Ryka AokiCall Number: Fic Aoki, Ryka
When Katrina Nguyen, a young transgender runaway, catches Shizuka's ear with her wild talent, Shizuka can almost feel the curse lifting. She's found her final candidate. But in a donut shop off a bustling highway in the San Gabriel Valley, Shizuka meets Lan Tran, retired starship captain, interstellar refugee, and mother of four. Shizuka doesn't have time for crushes or coffee dates, what with her very soul on the line, but Lan's kind smile and eyes like stars might just redefine a soul's worth.
