Karigan may have heard the First Rider's call, but she's not about to let it take over her life ...
... or at least that's what she thinks. She swore to complete a dying man's mission - to deliver a sealed letter to King Zachary.

Exhausted in both body and spirit, she plans to return to her quiet life and her father's business.

Karigan resists it, but when she wakes up to find herself - in her nightdress - on horseback and halfway across the country, her destiny is clear: she is a Green Rider.
As she discovers, it's not a good time to be called to serve.

For a thousand years the forest, an arboreal prison containing one of Sacoridia's greatest enemies, has been quiet. Not any more. The wall has been breached, unnatural, lethal creatures are finding their way into Sacoridia, a dark sentience is stirring, and the Green Rider magic itself is failing. And in the midst of it all, Karigan is about to be called to her duty ...
