"As Earth's ability to support human life begins to diminish at an alarming rate, the Global Space Agency is formed with a single mandate: protect humanity from extinction by colonizing the solar system as quickly as possible. Venus, being almost the same mass as Earth, is chosen over Mars as humanity's first permanent steppingstone into the universe.
Arik Ockley is part of the first generation to be born and raised off-Earth. After a puzzling accident, Arik wakes up to find that his wife is almost three months pregnant. Since the colony's environmental systems cannot safely support any increases in population, Arik immediately resumes his work on AP, or artificial photosynthesis, in order to save the life of his unborn child."
