The Stones of Kaldaar by Tameri Etherton

Some say she’s the one of prophecy,
that she’ll bring balance to the world.
Others say she’s the destroyer,
meant to bring an end to Aelinae.
They’re both right.

Everything Taryn knew was a lie. Her life on Earth, the man she thought was her grandfather, even her age, were all fabrications meant to protect her, to keep her hidden until she could return to her home world. Once on Aelinae, Taryn realizes she has more to fear than the creeping darkness that threatens to suffocate her.
Unwilling to become a pawn in the machinations of her scheming family and the world she now calls home, Taryn sets out to learn about her mysterious powers. Reluctantly, she accepts the help of Rhoane, a man who promises to protect her, but whom she's not sure she can trust.
As tensions mount and her loved ones are threatened, Taryn must confront an ancient enemy and stop a sinister plan to bring back a banished god.
On Aelinae they say there can be no Light without Dark and no darkness without light. If Taryn fails, there will be only Blackness. Absolute. Binding. Without end.
Failure is simply not an option.

“The world of Aelinae and the people that inhabit it explodes across the pages like a beautiful display of richly colored fireworks!” Carol Conley, InD'Tale Magazine ★★★★★ Stars
