Year 2218.Why does a man, haunted by a profound encounter with an alien intelligence and stalked by a devastating addiction, accept an impossible mission to save humanity from certain annihilation? Because he is Aiden Macallan, commander of the Sun Wolf, and those afflictions make him the only person for the job.
After fifty years of enabling human expansion into Bound Space, the enigmatic voidoids are beginning to shut down. No one knows why, or who's behind it, but one thing is certain: if all the voidoids disappear, not only is humanity locked out of Bound Space forever, but it will unleash a torrent of dark energy tearing our universe apart, from atoms to stars. It will happen soon and happen fast unless Aiden and his hand-picked crew can stop it.
But as they set course for the Frontier in search for answers, someone is trying to stop them, attacking from the shadows at every step of the way. Someone who just might want the destruction of the voidoids to proceed. Now, in a race against time and malevolent forces, light-years from home, the Sun Wolf is humanity's only hope for survival.
