My Happy Life (2002)

Brief but weighty, her third book, My Happy Life (2002), is a poetic, language-oriented work about a lonely misfit trapped in an abandoned hospital, who writes the poignant story of her life on the walls. It is narrated by, as the Village Voice glowing deems her, "an orphan cruelly mistreated by life who nevertheless regards her meager subsistence as a radiant gift." Despite the horrors that amount to her life, she still calls herself happy. Jennifer Reese of The New York Times Book Review commented on Millet's new approach to the treatment of the literary victim, saying "Millet has created a truly wretched victim, but where is the outrage? She has coolly avoided injecting so much as a hint of it into this thin, sharp and frequently funny novel; one of the narrator's salient characteristics is an inability to feel even the mildest indignation. The world she inhabits is a savage place, but everything about it interests her, and paying no attention to herself, she is able to see beauty and wonder everywhere."

Everyone's Pretty (2005)

Millet's fourth novel, Everyone's Pretty (2005), is a picaresque tragicomedy about an alcoholic pornographer with messianic delusions, based partly on Millet's stint as a copy editor at Larry Flynt Publications. Sarah Weinman of the Washington Post Book World called it "both prism and truth" "With a sharp eye for small details, a keen sense of the absurd and strong empathy for its creations," Millet creates a kaleidoscope of quirky characters. The New York Times Book Review called her fifth novel, Oh Pure and Radiant Heart (2005), an "extremely smart…resonant fantasy." It brings three of the physicists responsible for creating the atomic bomb to life in modern-day New Mexico, where they acquire a cult following and embark on a crusade for redemption.

How the Dead Dream (2008)

How the Dead Dream is "a frightening and gorgeous view of human decline," according to Utne Reader. It features a young Los Angeles real estate developer consumed by power and political ambitions who, after his mother's suicide attempt and two other deaths, begins to nurture a curious obsession with vanishing species. Then a series of calamities forces him from a tropical island, the site on one of his developments, onto the mainland where he takes a Conrad-esque journey up a river into the remote jungle. Eye Weekly summarized this black comedy, noting "American culture loves its stories of hubris, downfall and ruin as of late, but it takes a writer of Millet's sensitivity to enjoy the way down this much."

Love in Infant Monkeys (2009)

Love in Infant Monkeys is a short story collection featuring vignettes about famous historical and pop culture icons and their encounters with other species.

Ghost Lights (2011)

Her 2011 novel, Ghost Lights, made best-of-the-year lists in the New York Times and San Francisco Chronicle and received strong critical attention. The novel stars an Internal Revenue Service bureaucrat named Hal — a man baffled by his wife's obsession with her missing employer. In a moment of drunken heroism, Hal embarks on a quest to find the man, embroiling himself in a surreal tropical adventure (and an unexpected affair with a beguiling German woman). Ghost Lights is beautifully written, engaging, and full of insight into the heartbreaking devotion of parenthood and the charismatic oddity of human behavior. The Boston Globe called it "[An] odd and wonderful novel", while the Cleveland Plain Dealer wrote, "Millet is that rare writer of ideas who can turn a ruminative passage into something deeply personal. She can also be wickedly funny, most often at the expense of the unexamined life."

Ghost Lights was the second in an acclaimed cycle of novels that began with How the Dead Dream in 2008. The third, Magnificence (2012) completes the cycle.

Magnificence (2012)

Magnificence introduced Susan Lindley, a woman adrift after her husband's death and the dissolution of her family. Embarking on a new phase in her life after inheriting her uncle's sprawling mansion and its vast collection of taxidermy, Susan decides to restore the extensive collection of moth-eaten animal mounts, tending to "the fur and feathers, the beaks, the bones and shimmering tails." Meanwhile, an equally derelict human menagerie – including an unfaithful husband and a chorus of eccentric old women – joins her in residence. In a setting both wondrous and absurd, Susan defends her legacy from freeloading relatives and explores the mansion's unknown spaces. Jonathan Lethem, writing for The Guardian, called it "elegant, darkly comic…with overtones variously of Muriel Spark, Edward Gorey and J. G. Ballard, full of contemporary wit and devilish fateful turns for her characters, and then also to knit together into a tapestry of vast implication and ethical urgency, something as large as any writer could attempt: a kind of allegorical elegy for life on a dying planet. Ours, that is." The book was nominated for a Los Angeles Times Book Prize.

Shimmers in the Night (2012)

The September 2012 release of Shimmers in the Night was the second in The Dissenters, an eco-fantasy series for young adults. Beginning with The Fires Beneath the Sea, the plot follows two young siblings as they search for their mother, a shapeshifting character who is fighting against forces who wants to make the planet over in their own image.

Pills and Starships (2014)

Pills and Starships is a young adult novel set in "a dystopic future brought by global warming."

Mermaids in Paradise (2014)

Mermaids in Paradise tempers the sharp satire of Millet's early career with the empathy and subtlety of her more recent novels and short stories. In a send-up of the American honeymoon, "Mermaids in Paradise" takes readers to the grounds of a Caribbean island resort, where newlyweds Deb and Chip — the opinionated, skeptical narrator and her cheerful jock husband — meet a marine biologist who says she's sighted mermaids in a coral reef. Karen Russell wrote "leave it to Lydia Millet to capsize her human characters in aquamarine waters and upstage their honeymoon with mermaids. I am awed to know there's a mind like Millet's out there – she's a writer without limits, always surprising, always hilarious."

Sweet Lamb of Heaven (2016)
