Tasman is born into a world populated by two-headed bicephalic "twins" who share one body. Alone, she struggles for acceptance and becomes the unwitting key to the Earth’s salvation, in a poetic and apocalyptic vision of the future where technology exists as a mere remnant of a destroyed world, conjoined twins are the norm and the orbit of the moon is decaying.

In the second book of the Moonfall Trilogy, the story continues in a post-holocaust world inhabited by bicephalic humans - two-headed twins sharing the same body. With the birth of a new religion, which makes its saviors into victims, the children of Atwar must complete the prophecy of Moonfall.

In the far future, deadly radiation from atomic conflict has caused humanity to mutate into two-headed or bi-cephalic people, who are essentially twins inhabiting one body. In the Moonfall series, readers follow one-headed Tasman and her family, witnessing their development from outcasts to heroes, the only ones able to fit into the ancient spaceships and save the Earth from the threat of the moon's unstable orbit. The Taming, sequel to Moonfall and The Children of Atwar, concludes the epic saga of humanity's strange future.
