Carbon Dreams, Susan M. Gaines

At an oceanography institute in northern California, geochemist Tina Arenas studies climates of the distant geologic past. Heedless of life beyond her circle of scientists, Tina is immersed in a world of dinosaurs and shifting continents, where time is measured in ten-million-year spans—but when both her research and an extracurricular love affair take off in directions she has not anticipated, she is catapulted into the late twentieth century world of people and politics.
