To be a seeker

Althea is born to a simple cook. She lives a normal life. But she bears the mark of a seeker. She is one of the few people who can see the Invisible Tribe. A group of peaceful predators that can't be seen. She runs away from the king who wants her to seek war against the peaceful tribe. She now lives in a forest wanted for treason. She lives in peace until she finds 2 people wandering in the forest. Will they find out who she is?
