"Rin, Tongue, and Dorner takes place in an apocalyptic future, where humanity survives in temperature regulated geodomes. The protagonist, Dorner, has committed himself to his career as a Planner, keeping the temperature of his colony constant through a system of furnaces as well as a strict code of human conduct. Extremes of human activity -- violence, extreme athleticism, and excessive sexual activity -- can threaten the thermal balance. His vow of abstinence, however, is threatened by a presence that has haunted him from childhood. He seeks the help of Rin, a neurosurgeon, who unveils his past and his demons. As they discover their love for each other, each must decide how far they are willing to go in confronting their fears, accepting their inner shadows, and unleashing the power of their desires that can either save them or destroy everything they know"--Goodreads.com.
