Good Omens meets The Long Way to a Small, Angry Planet.
 
Shizuka Satomi is a brilliant, cursed violinist who must win her soul back from damnation. To do this, she must take seven prodigies as students, then entice each to trade their soul for fame. She has already delivered six.

However, rather than the usual pampered genius, the seventh, Katrina Nguyen, is a young transgender runaway with a wild talent, who is fleeing an abusive home. Meanwhile, Lan Tran, a starship captain, has crossed the galaxy with her family to make a new life running a local donut shop. But though she saved them from a galactic war, nothing can stop the end of existence itself.

Faustian bargain meets space opera in this genre-bending novel of three vastly different women. Bombarded by catastrophe, misunderstanding, and fate, each has come to San Gabriel Valley, just outside of Los Angeles, to escape their fates, find their voices, and save the universe.
