Array 2781 is the second of three full-length novels set immediately after the short story Hera 2781. The year is 2781. 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.
