   Summary

   On board the Hail Mary, the Xenonite wall between Grace and Rocky keeps both of them alive. But it's failing. In three days, the air that lets Grace breathe will kill Rocky. The ammonia that let's Rocky breathe would be lethal to Grace. And all the while, Grace fights his own problems as an illness drags him under just when he can least afford to fall apart.
