The planet of Azure is nearly idyllic - there is a high standard of living, industry is booming, and the two races - Human and Wrogul - get along well with each other most days.But underneath it all, there is tension between the races. Despite having no reason for it, the Humans don't always trust the Wrogul, and there is a faction within the Wrogul community that doesn't want its young growing up "Human."When a large group of Wrogul move into the ocean and strange things begin happening - weird lights seen in the depths and sabotage at the mariculture stations - the Human's distrust becomes outright suspicion of treachery. As things spiral out of control, another force enters the system - a group ostensibly sent by the UN on Earth to inspect the crops being grown on Azure - which threatens to destroy everything the Humans and Wrogul have worked for.While the Wrogul still intend to do no harm, the Humans have powerful enemies in the galaxy, and, this time, the Wrogul may have no choice about whether to join the front lines with their Human friends. Will the threat of a common enemy break the relationship between the Humans and Wrogul...or break it not?
