Indigo Billy Ii: a Private War

As possibly the sole human left alive in the galaxy, Indigo Billy commands a warship and sets out to seek vengeance. The geshaanti not only killed, maybe, every human, but worse, they killed his only love. What Billy doesn’t yet know is there are forces, and intelligences greater than his own, that pursue him. Revenge upon the geshaanti will have to wait while he works at simple survival.
