Ymir

A savage ritual threatens to set off a tide of violence throughout the Heracles Gulf.
Fresh off Tyunta and stripped of both Ardennes and his active status, Vandal must return to his home world and finish his jockey training before Colonel Swift secures a new contract. But when a new threat brews at the edge of the Heracles Gulf, Vandal faces being left behind if he can't finish in time. Deadly, secretive descendants of ancient Northmen raid isolated worlds. These savages, shot into space on the back of stolen technology, are committed to blooding their next generation of warriors. And the Chevaliers might be next in their cross hairs.
