In this space exploration adventure modeled on Ernest Shackleton's disastrous Antarctic expedition, Ruby Ladd is commanding the first crewed mission to the asteroid belt, ready to redeem herself after a tragedy on Mars five years earlier. She never asked for a nosy filmmaker whose search for a story will only reopen old wounds. A trip to the asteroid belt is just what Harte Gunner needs for his next thrilling documentary. He suspects the heart of his story lies in the commander's past. But she's not talking. When disaster strikes, Ladd and Gunner must work together for the crew to survive.
