The third in the Hugo, Nebula and Locus award-winning series

The Earth is growing ever hotter, as governments clash and riots and sabotage plague the space program. The IAC’s goal of getting as many people as possible off Earth before it becomes uninhabitable is under threat. 

The Moon colony is still being established, but Elma York is already on her way to Mars. Her friend and fellow Lady Astronaut Nicole Wargin is thrilled to be on the pioneering mission — but less happy that her husband, the Governor of Kansas, is considering a run for President.
