Cyraria is a hostile world with weather extremes beyond imagination. With Opposition, the worst portion of the heat season on the way, Dirck Brightstar and his father, Laren take on the challenge of modifying their primitive shelter to withstand the hostile environment in what is rapidly becoming a dystopian nightmare. Their attempt to build a heat exchanger (air conditioner) to maintain a survivable temperature is interrupted when Laren is arrested in a midnight raid and incarcerated as a political prisoner as a part of Augustus Troy's Integration recruiting efforts. Dirck is thus left on his own to fend for his family, more separated now than ever before. His friend, Win, proves to be a valuable ally though his little brother, Deven, becomes the real hero thanks to his strange alliance with an indigenous race known as the bnolar.Creena, another family member separated from the family in a previous incident, experiences increasing trouble as well when she and her 'troid, Aggie and vegemal, Thyron, land on a planet seeking a more capable vehicle for the trip back to the family's homeworld, Mira III, to obtain assistance. Their efforts are thwarted when authorities impound their ship and separate them as targets for government scrutiny and investigation. Creena's options are severely limited and further complicated by Integrator attempts to abduct her, the evil purpose of which she can sense but doesn't understand. With no other choice but to adapt to a primitive and alien lifestyle until her situation is resolved, when it finally comes time to leave she discovers she's grown more attached to this backward world than she ever thought possible.[NOTE:--Readers with a strong interest in science will particularly enjoy these stories in which the author demonstrates numerous scientific principles and their importance through entertaining plot action.
