Z for Zachariah is an post-apocalyptic science-fiction novel by Robert C. O'Brien that was published posthumously in 1974. The name Robert C. O'Brien was the pen name used by Robert Leslie Conly. After the author's death in 1973, his wife Sally M. Conly and daughter Jane Leslie Conly completed the book guided by his notes. Set in the United States, the story is in the form of a diary written from the first-person perspective of sixteen-year-old Ann Burden, who has survived a nuclear war and nerve gas through living in a small valley with a self-contained weather system.


According to Sally Conly, Z for Zachariah was her husband's second novel intended for adults, following his 1972 science-fiction thriller A Report from Group 17. O'Brien had previously established himself as a children's writer with his novels The Silver Crown (1968) and Mrs. Frisby and the Rats of NIMH (1971). Z for Zachariah received a 1976 honor award from the Jane Addams Children's Book Award and the Edgar Award for the best mystery fiction in the juvenile category.

Plot summary

Ann Burden is a teenage girl who believes she is the last survivor of a nuclear war. Since her family's disappearance on a search expedition, she has lived alone on her farm in a small valley spared from radiation poisoning. A year after the war, a stranger in a radiation-proof suit approaches her valley. Afraid he might be dangerous, Ann hides in a cave and does not warn the man when he mistakenly bathes in a radioactive stream. When he falls ill, her fear of being alone forever leads her to reveal herself to help him. She discovers that the stranger is John Loomis, a chemist who helped design a prototype radiation-proof "safe-suit" at an underground lab near Ithaca, New York. Ann moves him into her house and fantasizes about eventually marrying him.

As Loomis becomes more ill and delirious, he has traumatic flashbacks to the underground lab, and talks of how he shot his coworker, Edward, who tried to take the safe-suit to find his family. Though troubled by this revelation, Ann continues to nurse him through his illness and keeps secret her knowledge of Edward's death. As Loomis recovers, Ann is taken aback when he begins criticizing her farming and giving her orders. He forbids her to touch the safe-suit. He orders her to plant wheat and beets to preserve seed stock, and though she acknowledges this is sensible, his explanation that they have to plan "as if this valley is the whole world and we are starting a colony," makes her uneasy. Her uneasiness increases when she asks if he was ever married, and he grabs her hand roughly. He demands to know why she asked and refuses to let go of her until she answers, pulling her off balance until she falls and inadvertently hits his face. He rebukes her for this and does not speak of the incident again. One night soon afterwards, she awakes to hear Loomis in her room. When he attempts to grab her, she flees to the cave again.

After some days, Ann approaches Loomis and proposes sharing the valley and farm work but living apart. He professes surprise when she tells him she won't live with him anymore and asks why, as if he has no idea. Ann remembers that he acted the same after he had grabbed her hand, "as if nothing had happened, or as if he had forgotten it," She refuses to justify her choice to him, to tell him where she is living, or to come back to live with him. Loomis answers that he has no choice but to accept her proposal, though he hopes she will reconsider and "act more like an adult and less like a schoolgirl". Though the arrangement is "unnatural and uneasy," and Ann worries about surviving winter, she sticks by her decision and wishes Loomis had never come. Loomis begins depriving her of access to the tractor and store, cutting off her supplies. When she approaches the house, Loomis shoots her in the leg. Ann flees back to the cave, realizing that he had not shot to kill, only to lame her to make her easy to capture. Loomis uses her dog, Faro, to track her to the cave, where he burns her belongings, though Ann escapes. Ann's leg wound becomes infected. As she recovers, she has feverish dreams of another valley where children wait for her to teach them. Ann comes to believe the dreams may be true and Loomis is insane, so she plans to steal the safe-suit and find her dream valley. Moreover, she decides to kill Faro to prevent Loomis from tracking her in the meantime, though she is later unable to do so. However, Faro become fatally poisoned swimming across the dead creek to her.

Ann finally acts on her plan. She lures Loomis from the house with a note offering to talk if he meets her unarmed, then steals the safe-suit and waits for Loomis to arrived. When he does, she reveals her knowledge of Edward's murder, which shocks Loomis enough to stop him from shooting her. Though he begs her not to leave him alone, Ann is resolved to leave, but tells him she will send people to him if she finds any. Loomis's last action is to call out that he once saw birds circling to the west. Ann, heeding his advice, leaves the valley for the radiated zone, hoping to see a green horizon.


As a child, Ann had a Biblical ABCs book, with A for Adam and Z for Zachariah. She remembers thinking that if Adam was the first man on earth, Zachariah must be the last man.


The story's events are set almost entirely in Burden Valley, a small and remote valley somewhere in the USA. It was named after the protagonist's ancestors, who were its first settlers and built a farm in the northern end. The only other inhabitants were the Kleins, a couple who lived over the store and mainly did business with Amish farmers to the south.

The valley is approximately 4 miles long, from Burden Hill in the north to an S-shaped pass in the south called "the gap". The largest of its two streams, Burden Creek, is radioactive because its source is outside the valley. It runs parallel to the road from north to south and exits the valley through the gap. A smaller stream originates from a deep spring on an eastern hillside and feeds a small lake with fish that provide a food source for Ann. The stream then meanders south and joins Burden Creek. Much of the valley is made up of woodlands.

Ann initially thinks the animals in the Valley are probably the last of their species; however, at the end of the book Loomis reveals he has seen birds flying in the distance west of the valley, which opens the possibility of other life as well. There are rabbits and squirrels in the valley. There are also a few crows, which Ann believes survived because only they had the "sense" to stay in the valley, while other birds migrated. There are two cows, a bull calf, and chickens on Ann's farm. Finally, there is the dog, Faro, who belonged to Ann's cousin David.

The most important feature of the valley is that it is somehow separated from the surrounding atmosphere and has its own weather system. Loomis calls it a meteorological enclave created by an inversion (i.e., air only rising, not falling), but he views its existence as so unlikely that it is only a theoretical possibility. Loomis' scientific assessment seems correct because the air in a valley could not be separate from the planet's atmosphere unless the valley's walls were unbroken and rose as high as the tropopause, the level at which temperature begins to increase and air only rises. In any other situation, a valley's air would necessarily mix with surrounding air, and pollution would enter from above. However, for the purposes of this story, readers must suspend disbelief to accept that at least one valley with a self-contained weather system exists, allowing some life to continue after global nuclear war.

Major themes

Seeing the story as a conflict between an innocent girl and a domineering male scientist bent on controlling the valley, reviewers have found themes such as the destructiveness of science (at least when it is separated from conscience), the corrupting effect of the desire for power, and the moral value of individual freedom. Ann's sensitivity and love of nature are viewed as contrasting with Loomis's callous reasoning and selfish compulsion to take control. Writing for The Spectator in April 1975, Peter Ackroyd concludes that "science turns paradise sour." Reviews the same year in The Junior Bookshelf and Times Literary Supplement described Ann as an unwilling Eve who "finally refuses to begin the whole story over again."


In February 1984, the BBC presented a film adaptation for its Play for Today series in which the setting was changed from America to Wales.

Z for Zachariah, a 2015 film adaptation of the novel premiered in January 2015 with financing from Creative Artists Agency (CAA) and Material Pictures. Eschewing the central Adam/Eve theme and its deconstruction of abusive and controlling relationships, it adds a third character and involves a love triangle. It stars Margot Robbie, Chiwetel Ejiofor, and Chris Pine. Craig Zobel directs from an adapted script by Nissar Modi. Filming took place on New Zealand's Banks Peninsula and in the small former coal mining town of Welch, West Virginia.
