The Price Promised. Tales of Terra'valda, #1

There is one rule that a Sister should never break: The shaedborne are not to be trusted. To much of Terra'valda, Sisters are the subject of stories and songs, of frightened whispers in the dark. In the nation of Khaeton, they are commonplace. Both respected and feared, they are relied upon for their abilities and avoided for their 'dealings with the daemons.'  Dealings that grant them unimaginable power-at a cost.  The throne of Khaeton rightfully belongs to Rhedonne Vermillion.
They're subtle about it, but people want her dead. Her fellow Sisters would too if they knew the truth. She's hidden just how strong she is for one very deadly reason: she has learned her magics from the shaedborne themselves, a crime worthy of a prompt execution. or worse. A lifetime of caution and concealment is burned to ash when a town in an allied nation goes silent. There she finds countless innocents slain and more questions than answers.
To discover the truth, Rhedonne just might have to do what's long been impossible for her-learn to rely on others and reveal the very secrets she has guarded for as long as she can remember. The first book in the Tales of Terra'valda series, The Price Promised is a high-stakes tale of politics, mystery, and magic. Featuring difficult people in difficult situations, it's a story of duty, sacrifice, and a love so strong it hurts.
