The crew of Boundless are outlaws from the moment the giant colonist ship launches, thanks to a saboteur plot foiled by ship captain Reggie Paser. Outlaws or not, they have a mission to complete-the safe delivery of twenty-thousand colonists to a new world.

Alan and Nancy, both born on Earth, grow up in the confines of Boundless hulls, interacting with the alien Benai and the mysterious, powerful human Watchers. Through the Watchers' careful tutelage, the two develop mental powers well beyond the scope of most humans. The Watchers also introduce them and others on the crew to the wonders of pair-bonding-a deeply emotional and erotic relationship with unexpected benefits.

As Boundless delivers colonists and cargo between worlds, a threat to the crew, Earth, and all sentient beings stirs in a remote race of humans with roots in the Andromeda Galaxy. A highly xenophobic race is systematically wiping out life across entire solar systems. With Earth unaware of the danger, Boundless may be the only defense against interstellar genocide.

A stirring, romantic saga spanning fifty years, Boundless continues the story of space exploration begun in New Paradigm.
