A Feather So Black

Magic has gone from the kingdom since the Fair Folk took the High Queen's infant daughter and withdrew behind the sealed gates of Tir na nOg. Fia is the changeling left in the princess's cradle. She was raised in secret as a spy, and every part of her training points at one mission.

That mission becomes possible when a hidden gate into the otherworld is discovered. Fia is sent through to bring back Eala, her lost sister, who lives under a curse that turns her into a swan by day. She must also steal a powerful sword kept deep in the fae realm.

The gate lets Fia cross only on the full moon, and she has to be back before the moon wanes. The story runs across a year of these trips, each incursion more dangerous than the last, so the clock is always close. Rogan, the princess's betrothed and Fia's friend since childhood, goes with her.

In the fae realm she is pulled, against her own judgment, toward Irian, a shadowy fae warrior who stands between her and the sword.

This is an adult romantasy with explicit content, and the first book of the Fair Folk trilogy by Lyra Selene. It draws on Celtic mythology and combines elements of The Twelve Dancing Princesses and The Swan Princess.
