A world split in two. A mysterious stranger. A discovery that will change everything.

After a brutal, sweeping plague decimated the Earth, the world is split in two. Above, the elite live in opulent skycities, while those who remain on the ground-terrestrials-struggle in settlements strewn across the dying planet.

Eighteen-year-old Terra Rhodon ekes out a meager living as a scav, scouring the earth for skycity scraps and doing whatever it takes to keep her younger brother safe. But when a routine scavenging run uncovers a dangerous secret-and an even more dangerous skydweller-Terra finds herself pulled into a conspiracy that could shatter everything she thought she knew about the world, her family, and herself.

TERRESTRIALS brings together both books of Gretchen Powell Fox's YA dystopian sci-fi duology-Terra and Underground-for the first time. Perfect for fans of The Hunger Games, Divergent, Shatter Me, and The Lunar Chronicles.
