"This is a major novel, and a notably audacious one. Lacey is pulling from a deep reservoir. Beneath the counterfactuals, and the glamour and squalor of Manhattan nightlife, and the mythologies bought and sold, she's telling a love story of a broken sort. C.M. is flinging rope between her present and past. This book is about facing, and accepting, the things you didn't want to know." --Dwight Garner, The New York Times

"Lacey imposes a truly outstanding narrative authority on her pseudo-biography . . . the audacity of this book . . . seems likely to bring her to a much wider audience. If this does mark Ms. Lacey's deserved elevation to mainstream attention, she has accomplished it without diluting the vital qualities of confusion, yearning and mystery." --Sam Sacks, The Wall Street Journal

"[A] staggering achievement . . . [a] masterpiece about the slippery nature of art, identity, and truth." --Adrienne Westenfeld, Esquire

"Brilliant, astonishing . . . The book is a marvelous centrifuge, in which political and cultural histories of the American 20th century collapse." --Chris Kraus, The Washington Post

"Genre-quaking . . . A true magnum opus . . . [X is] an unstable new element in the periodic table of literature." --Hillary Kelly, The Atlantic

"In its boldness of premise and execution, Biography of X goes above and beyond, under the river and through the woods. It flaunts world-building skills that the writers of HBO's "Game of Thrones" wish they'd had . . . Lacey is one of the most fearless novelists writing today." --Jessica Ferri, Los Angeles Times

"Haunting, genre-bending . . . It's like looking at a family photograph in which something truly extraordinary - an avalanche or alien invasion - is taking place in the background . . . A lovingly made facsimile of a nonfiction book, Biography of X resembles a Tlönian artefact from a parallel reality. Though it may not change the world, it will leave the reader altered." --Marcel Theroux, The Guardian

"Lacey has done such a brilliant job of making X impossible to envision, impossible to feel or grasp . . . There is an ambition in The Biography of X that's thrilling not least because it shows how endless, how elastic and expansive--at a time when so much storytelling feels constricted, tight and close on a single consciousness--fiction can be." --Lynn Steger Strong, The New Republic

"A Scheherazade-like sequence of stories. Most of these stories are about the charismatic X's life and fabrications; all of them are arresting in their originality; and, the final story that CM is led to, housed in a storage facility, is devastating . . . Just when you think you have a handle on Biography of X, it escapes the stack of assumptions where you thought you'd put it, like a profile or an obituary you'd started reading in yesterday's tossed-out paper." --Maureen Corrigan, NPR's Fresh Air

"Lacey's fifth book bursts with urbane vitality. The author convinces us by the sheer inventiveness of her artifice . . . Biography of X is the author's most ambitious and enjoyable novel yet, filled with the subversive humour and verve only hinted at in her previous books . . . Catherine Lacey is clear-eyed about human dependency and self-delusion." --Jude Cook, TLS

"a towering work that comments on, among things, art-world ridiculousness, the elasticity of identity, culture divides in the United States, and the fool's errand of compressing a life into narrative . . . Beyond the book-as-book exercise, Lacy's inventiveness when describing X's various attention-grabbing exhibitions, and the genius visual annotations, Biography of X consistently stuns on a sentence-to-sentence basis. This is a wise, wise work." --Rich Juzwiak, Jezebel

"Lacey artfully blends historical anecdotes--X is seen penning songs for David Bowie and attending openings with Richard Serra--into her fictional universe, making uncomfortable connections between X's fragile world and our own." --The New Yorker

"Bold and exhilarated, figuring itself out as it moves forward, an act of raucous creativity." --Jackie Thomas-Kennedy, Minneapolis StarTribune

"Brimming with negative capability, intrigue, and erudition, Biography of X is at once a tense, tongue-in-cheek cautionary tale for the United States and a robustly supported argument for the idea that biographical knowledge alters the reading of an artwork." --Jenny Wu, Los Angeles Review of Books

"Lacey is brilliant. As in her earlier fiction, she is thinking deeply about what we give up to other people when we love them . . . in Biography of X, she has reached a new level of understanding." --Emma Alpern, Vulture

"Biography of X is criminally good, building on [Lacey's] previous five books' fascination with the mutability of self with kaleidoscopic depth and astonishing propulsion . . . What is most spectacular is Lacey's sleight of hand, inviting us to become engrossed in the unknowability of others, while gently reminding us that we, too, are unknowable--even and especially to ourselves." --Ayden LeRoux, BOMB

"Sweeping, ambitious . . . too expansive to simply be called a novel . . . The book is a provocative project--one that mirrors and refracts our own cultural obsession with celebrity and our nation's broken politics." --Sammy Loren, Document

"One of the most inventive works I've read in a long time, Catherine Lacey's latest novel is a must-read for fans of ambitious, genre-bending literary fiction." --David Vogel, Buzzfeed

"Breathtaking in its scope and rigor, this unforgettable novel pushes contemporary fiction to dizzying heights. A triumph." --Kirkus (starred review)

"An audacious novel of art and ideas . . . The author also perfectly marries her [character's] history with her study of a shape-shifting artist, with X refashioning herself both to escape her ultraconservative homeland and to build a vehicle for her creative expression. This is brilliant." --Publishers Weekly (starred review)

"A dazzling literary chimera, at once an epic and chilling alternate history of the United States and an intimate portrait of a woman coming apart at the seams." --BookPage (starred review)

"A tour-de-force in literary and artistic realms, this engrossing story of breakaway artist X will challenge readers on many levels." --Library Journal (starred review)

"Lacey's tale is a lovely meditation on not only the mysteries of grief and love but also the equally mysterious ways of the creative process." --Booklist

"Sly, brilliant, philosophically acute, bitingly funny, and a pure joy to spend hours with . . . Suffice it to say that it feels fairly rare for a novel to be hugely intelligent and moving and fun in equal measure, but with Biography of X, Catherine Lacey somehow--magically--makes the nearly impossible look easy." --Lauren Groff, author of Matrix

"I'm not sure I know another novel that manages to be so many books at once: a biography revealing masks beneath masks and faces beneath faces, a quest narrative unsure of what it's seeking, an impossibly ambitious parable about art and the enigma of others, an alternate history of America that serves as an X-ray of our own fractured country. Biography of X is a profound novel about love and what it can license, about the toll--and maybe the con--of genius. Only Catherine Lacey could have written it." --Garth Greenwell, author of Cleanness and What Belongs to You

"Biography of X is the most ambitious book I've ever read from a writer of my own generation. Epic world-building revealed through intimate emotion and dangerously honed sentences; a story that mixes fact and fiction to create a new register of truth, a register that belongs entirely to Catherine Lacey. I'm awed." --Torrey Peters, author of Detransition, Baby

"Biography of X is a triumphant high-wire act: all the breadth of a 19th century classic with the propulsiveness of a psychological thriller. I stayed up too late, wishing to uncover X's secrets alongside the narrator." --Sara Novic, author of True Biz
