Any Moment, the Veil of Visible Light

Eiru’s best friend Kenis has just betrayed their devout, secluded village to an empire greedy for its magic — and Eiru knows exactly how her village expects her to fight back. Just kill Kenis and kill the imperialists with her rare and precious powers, and Eiru can save her family’s magic and their whole blessed valley.

Or Eiru could try to figure out why Kenis betrayed them. Give Kenis just one more chance. She can’t possibly be the heartless apostate the village has decided she is.

Unless Eiru’s feelings are a little more compromised than she thought...or the blessed valley is hiding something.
