First Rider's Call (2003) is the second novel written by Kristen Britain and is the second book in its series. Plot summary Now a Green Rider, one of the king's elite troop of messengers, Karigan returns to Sacor City, giving up her merchant lifestyle. The story opens a year into this service as danger is threatening the kingdom of Sacoridia once again. The dark magic in Blackveil Forest is restless, and has found an outlet through the breach in the D'Yer Wall, which has protected Sacoridia from the forest for over 1000 years. This influx of magic has interfered with a land that has largely learned to live without magic during this time. Reports of strange instances of animals turned to stone and entire villages disappearing are brought to the palace from around the country. In the end the strange magic touches even the main city as suits of iron are brought to life and snow falls within the castle. Even the Green Riders' magic is affected, sending Captain Mapstone into self-imposed solitary confinement. As a result, Mara, another rider, and Karigan are left to lead the riders as best they can. Throughout the book Karigan has ghostly visions of Lil Ambriodhe, First Rider, legendary founder of the Green Rider messenger service. Karigan meets with an Eletian prince and learns that she has wild magic within her that entered her as a result of her battle with Shawdell in the previous book. This wild magic augments her rider ability and allows her to travel through time, even visiting Lil Ambriodhe in her own time. Unfortunately, the magic also allows Mornhavon the Black to possess her. However, Karigan uses this to her favor---while Mornhavon possesses her, she transports him into the future, and, with the help of Lil Ambriodhe, she deposits him there. This buys the defenders of Sacoridia time to prepare for Mornhavon's return. With the weakening of the wall, Mornhavon's spirit reawakens in Blackveil Forest and begins to control the forest. Alton D'Yer is sent to fix the wall, but is betrayed by Seargent Uxton and knocked over the side of the wall into Blackveil. Mornhavon then possesses Alton and tricks him into singing the song that would destroy the D'Yer Wall, keeping him imprisoned. Mornhavon also raises two lieutenants from his army from the dead but they are later destroyed. Excerpts woven throughout the book are entries from
