Shrouded Kingdom (The Lost Queen of Althea Book 1) by Rachel Medhurst

Once a human, now a fae princess, destined to be queen.

Layanna Fairling has never belonged to her village, and yet, when it’s threatened by a tyrant who wants her dead, she knows she has to protect it.

Three mysterious strangers who claim Layanna is a changeling and future ruler of the Seelie Court arrive to aid her. They also claim that the only way of saving her village is by overthrowing the Unseelie tyrant who inherited the throne from his evil father when he slew her real parents, the Fae King and Queen of Althea.

The tyrant's greed and violence threaten to tear apart the kingdom she never knew existed, leaving Layanna with a simple choice. Overthrow the handsome and powerful tyrant, or lose everyone and everything she loves.
