1998 Paperback. Good used condition. By Kristen Britain. From the publisher: “Taking on the golden-winged horse brooch that is the symbol of the Green Riders, Karigan is swept into a world of deadly danger and complex magic, her life forever changed. Compelled by forces she cannot understand, Karigan is accompanied by the silent specter of the fallen messenger and hounded by dark beings bent on seeing that the message, and its reluctant carrier, never reach their destination.”
