Shivering World (Tyers, Kathy)

Dr. Graysha Brady-Phillips is suffering from a genetic disease that causes weakness and early death. When she is offered a position on planet Goddard, where the average life span exceeds 150 years, she leaps at the chance. The colonists' radical-and illegal-science just might be her only hope for a cure. Graysha must convince a group of paranoid rebel scientists to trust the daughter of their worst enemy, her mother.
