Years after their father’s disappearance on the maiden voyage of his exploratory space ship, The Outer Heaven, the four Angelus brothers had gone their separate ways. Savos—the prodigal son—grew detached from his surroundings and moved abroad in an attempt to find his place in the world. His eldest brother Davriel, enlisted in the United Terran Federation Marine Corps, while his fraternal twin Jonos followed a childhood interest in aviation, and his youngest brother Cephus enrolled in the UTF Naval Guard Academy. 

 

After several years of unsuccessful searching, Savos now returns to his hometown and reunites with his twin brother Jonos—a highly skilled pilot and flight instructor. Together, the twins will discover a secret about their father so massive that it shatters their perception of life itself. Fate intervenes when they are further united with their two Half-brothers and together they embark on a journey of discovery and peril while tracing their father’s footsteps and forging further into the final frontier.
