More than two hundred years into the future, human beings are an endangered species. The planet has been battered by war, its inhabitants plagued by disease and death. Few humans survived and remained unaffected. Most changed dramatically and evolved into something else entirely. Irrevocable alterations caused by chemical warfare have created a new species. North America is in ruins and has been overtaken. Humanity has fallen at the hands of mutants known as Urthmen. Seventeen year-old Avery is alive and unchanged. But she has not been immune to the harshness of the new world. She has lived on the run for much of her life, in terror. After fleeing the only refuge she's known for much of her life, Avery, along with her sister June and new friends, Will, Oliver and Riley forge through the forest to uncharted territory in search of a better life, in search of other survivors. But Avery soon learns that life beyond the woods is far worse than she ever imagined. She finds that safety does not exist for human beings in a world run by Urthmen. Hope seems futile. But Avery refuses to surrender hope and chooses, instead, to push forward and move her group into the heart of danger, to seek out more humans. Will she and the others survive their journey into the savage lands of Planet Urth? Find out in this heart pumping second installment of the Planet Urth series.
