Stoney Planet The Adventures of Izzy's Universe oleh Christopher M. Perkins

As the victims of an evolutionary disaster called Galactic Whip Singularity, the Popau escaped extinction by leaving their doomed solar system in search of other habitable worlds. Traveling throughout the 22nd tendril of our galaxy, they found numerous less advanced societies with which to carry on trade. Upon the establishment of intergalactic trade laws, they discovered that they could steer the economies of their inferior partners thus spurring on the Popau's rise to an empirical power. On the brink of first contact, Stoney Planet details the progression of a planetary usurption by the Popau. Through a plan laid out thousands of years in advance by the galactically renown agro-engineer E'deen, the Cannabis plant found itself at the center of society's battle to think freely. In an attempt to expose the oppressive campaign, a small group of unlikely heroes emerge to fight the prohibitionary tactics of the Popau only to find themselves in a much deeper conspiracy compounded by the potencial destruction of their own world brought about by the negligent procedures of a cumbersome empire.
