Where have all the Humans gone?

The Earth is dead. Its burnt out shell is being mined for remnant plastic by the Slidge in their quest to remember how to repair their failing technology. The vast Human empire, The Unison is no more. Humanity itself has disappeared, reduced to its four most insignificant specimens. Only two of whom are fertile.
Join Tuesday, Trace, Lana and Jimmy in the final thrilling, hilarious installment of the Scum of the Universe trilogy.
Follow the last Humans in the universe as they race to save the Milky Way galaxy from imminent Slidge invasion. Find new friends in strange places and old enemies where they least expect them. And save the Human species from complete annihilation. All without killing each other in the process... Spug, we're screwed!
