There's a traitor among the riders.
The Citadel is attacked, and the already weakened Order must face a new threat - one that isn't just flesh and blood.
Eldwin is summoned by the Assembly to fulfill his oath. To stop the coming darkness from spreading, he must venture into the Void, the realm between the living and the dead.
As cities fall and lives are lost, the scattered riders will need more than magic and dragons ... they'll need the Assembly.
Fans of Sarah K.L. Wilson's Dragon School, Christopher Paolini's Eragon and Anne McCaffrey's Dragon Riders of Pern will feel right at home.
The Dark Rider is the tenth episode of the series Dragon Riders of Osnen.
