Crimson
Aether

In the Kingdom of Asteria, a red letter changes everything. Cass, a former captain of the Blood Wings, and Claire Ashwood, a mercenary swordswoman with nothing left to lose, take a contract that leads them far from the capital of Velareth — down roads where bandits are the least of what waits in the dark.

A crimson power is spreading through the world, and the forces that seek to control it do not care who bleeds.
