The Death Of Grass
John Christopher
 A new virus strain has infected rice crops in East Asia causing massive famine; soon a mutation appears which infects the staple crops of West Asia and Europe such as wheat and barley, all of them types of grasses (thus the novel's title), threatening a famine engulfing the whole of the Old World, while Australasia and the Americas attempt to impose rigorous quarantine to keep the virus out. The novel follows the struggles of architect John Custance and his friend, civil servant Roger Buckley, as, along with their families, they make their way across an England which is rapidly descending into anarchy, hoping to reach the safety of John's brother's potato farm in an isolated Westmorland valley. Picking up a travelling companion in a gun shop owner named Pirrie, they find they must sacrifice many of their morals in order to stay alive. At one point, when their food supply runs out, they kill a family to take their bread. The protagonist justifies this with the belief that "it was them or us." By the time they reach the valley, they have accumulated a considerable entourage as a result of their encounters with other groups of survivors along the way. They find that John's brother is unable to let them all in to the heavily-defended valley. Pirrie acts to prevent John leaving the group and taking only his immediate family into the valley; instead, the group takes the valley by force. Pirrie and John's brother are killed; John takes possession of the valley.
