Array 2781 is the third part of the 2781 sequence featuring Drago Tell Dramis as a newly qualified fighter pilot, and best read after Hera 2781 (A Drago short story) and Hestia 2781 (A Drago novel) Drago has now learned the secret that his Betan clan has been hiding for almost a decade. He's currently alternating between moods of pitying his second cousin and fighter team leader, Jaxon, and wanting to strangle him. They both have to put their feelings aside though, and concentrate on using lumbering solar array transport ships to help with the repairs of the five Earth solar arrays, because Earth is critically short of power. Fortunately, repairing solar arrays is perfectly routine work, so Drago definitely can't get into trouble. Cover depicts the solar array transport ship, Antares.

Hestia 2781 is the first of two full-length novels set immediately after the short story Hera 2781. The year is 2781. Lieutenant Drago Tell Dramis’s first mission as a newly qualified fighter pilot ended with him and his team leader saving one of humanity’s oldest colony worlds, Hera, from destruction. Now he’s discovering that saving a world can be simple compared to living with the consequences. Both Drago and his team leader and second cousin, Jaxon, are famous now, given rapid field promotions, and are due to be awarded medals. Worryingly, Drago learns Jaxon has a mysterious secret and a past history of erratic behaviour. It’s vital that Drago keeps both of them out of trouble and away from nosy reporters until the medal ceremony, because Jaxon could do or say something that deeply embarrasses both the Military and their Betan clan. The Military is helping by sending their fighter team on a mission somewhere inconspicuously boring until the medal ceremony. That destination definitely won’t be Hestia, the perpetual trouble spot of humanity.

Sol 2781 is the third of three full-length novels set immediately after the novelette length short story Hera 2781. Major Drago Tell Dramis is celebrating the fact that the saboteur has been caught, and the Earth solar arrays will be safe now. The arrest of a member of the main board of Hospital Earth has consequences though. As Drago hits orbital levels of fury, and declares his own personal war against Hospital Earth, he’s hit by even more unexpected problems. There’s a joke that says one birth member of the Tell clan attracts trouble, two birth members of the Tell clan invite minor disasters, while three is the critical mass that triggers cataclysmic events. As the danger mounts, the question is whether Drago and his two cousins, Jaxon and Gemelle, can prove an alternative theory. Are three members of the Tell clan really the critical mass that resolves cataclysmic events? This extra-long novel concludes the Drago Tell Dramis 2781 sequence of Hera 2781, Hestia 2781, Array 2781, and Sol 2781.
