I'm pretty sure this was purchased at the friends if the library book sale nook as I found it in a bag of registered and unregistered books purchased in 2015 and 2016. I know I picked it up to read. However I have discovered this to be a second copy so will be sending it on it's way unread

Amazon Editorial Review

Magic, danger, and adventure abound for messenger Karigan G'ladheon in the second book in Kristen Britain's New York Times-bestselling Green Rider fantasy series • "First-rate fantasy." —Library Journal

Karigan G'ladheon was once a Green Rider, one of the king of Sacoridia's elite magical messengers. In the messenger service, she was caught up in a world of deadly danger, and though she defeated the rogue Eletian who cracked the magical D'Yer Wall—which had protected Sacoridia for a thousand years from the dark influence of Blackveil Forest, and Mornhavon the Black's evil spirit imprisoned within it—she had nonetheless been tainted by his wild magic.

Exhausted in body and spirit, and determined to take control of her own destiny, Karigan returned to her home in Corsa. But even Karigan's stubborn determination is no match for the Rider's call. Ghostly hoofbeats echo in the deep regions of her mind. When she awakes to find herself on horseback, halfway to Sacor City in her nightgown, she finally gives in.

Karigan returns to the court, only to find the Green Riders weakened and diminished. Rider magic has become unreliable, and she herself has ghostly visions of Lil Ambriodhe, First Rider, and founder of the Green Rider corps.

But why is the First Rider appearing to Karigan? And will Karigan be able to seek the help of a woman who has been dead for a thousand years?
