In the future, in a world baked dry by the harsh sun, there are those
who live inside the wall and those, like sixteen-year-old midwife, Gaia
Stone, who live outside. Gaia has always believed it is her duty, with
her mother, to hand over a small quota of babies to the Enclave. But
when Gaia's mother and father are arrested by the very people they so
dutifully serve, Gaia is forced to question everything she has been
taught to believe. Gaia's choice is now simple: enter the world of the
Enclave to rescue her parents, or die trying.
