NEW YORK, June 16, 2026 — Katie Couric announced today that her book club has selected SOMEONE ELSE’S HUSBAND by Kimberly McCreight as its featured title, delivering a significant platform to what is, on the evidence of the novel itself, the most ambitious book of McCreight’s twenty-year career. Published today by Knopf, the novel is a character-driven suspense narrative built around two women whose lives collide across an ocean, a mountain, and a set of secrets that neither of them fully controls.

McCreight has been one of the most reliable practitioners of intelligent suspense working in American fiction for a decade. Her earlier novels (RECONSTRUCTING AMELIA, WHERE THEY FOUND HER, A GOOD MARRIAGE) built her a devoted audience of readers who trust her to deliver suspense that respects them. SOMEONE ELSE’S HUSBAND is the book in which that trust is repaid at scale.

What the Book Is

Gretchen Falk is the woman most novels about wealthy Manhattan marriages spend four hundred pages punishing. Park Avenue. Three children. A husband, Richard, whom she genuinely loves and who genuinely loves her back. A life built with the deliberate care of a woman who has never taken for granted that any of it could hold.

Frankie Callahan is the woman most novels about ambitious young artists spend four hundred pages celebrating. A career-making show at a celebrated New York gallery. A shot at the kind of financial independence that would free her, at last, from a past and a man she has been trying to leave for years.

The two of them do not know each other. They meet on Mount Kilimanjaro, where Richard has traveled to climb with a group of old college friends, and where Frankie has traveled to mark the end of one chapter of her life before another begins. What happens on the mountain is not, in itself, the novel’s central event. The novel’s central event is what happens two weeks later, when the group returns to New York with one fewer member than it started with, and, shortly after that, when Frankie is found dead in her East Village loft.

Richard is charged with her death. Gretchen, the wife who was not on the mountain, is left to reconstruct what her husband is capable of and what she is capable of believing.

Why McCreight’s Craft Matters Here

The premise of SOMEONE ELSE’S HUSBAND could, in less careful hands, be a familiar novel. Wife-and-mistress fiction has a long shelf. What McCreight does, and what elevates the book, is refuse the shortcuts the premise usually invites. Gretchen is not naive. Frankie is not manipulative. Neither woman is the villain of the other’s story. Both are trying, in the ways their lives have taught them to try, to protect what they have built. The tragedy is not that one of them is right and one of them is wrong. The tragedy is that both of them are working with incomplete information, and that Richard, the man at the center, is not quite the man either of them believes she is loving.

The novel’s most quoted early line captures its emotional argument precisely: You had to rely on the power of love. That he loved you enough not to do the thing that would break your heart. It was paper-thin ice on which to stake your survival.

That sentence is doing a great deal of work. It is a statement about marriage. It is a statement about class, and about what a woman like Gretchen has staked on her ability to trust the person she chose. It is a statement about the ice itself, thin and clear, on which so many marriages are quietly built and rarely acknowledged to be built.

Why the Couric Selection Matters

Katie Couric’s book club has, since its launch, developed a specific and useful editorial sensibility. Couric selects books that combine narrative propulsion with real substance, that hold up under book club discussion, and that give readers something to argue about that is not merely plot. SOMEONE ELSE’S HUSBAND fits her curatorial voice with unusual precision. It will be discussed in book clubs from June through August. It will be argued about. Readers who identify with Gretchen will fight with readers who identify with Frankie, and both groups will finish the argument having had to reconsider their positions.

That kind of durable argumentative energy is not accidental. It is what a certain caliber of suspense writer can do when she takes her genre and her characters seriously in equal measure. McCreight has been doing this quietly for years. SOMEONE ELSE’S HUSBAND is the book that will make it impossible to miss.

The Verdict

SOMEONE ELSE’S HUSBAND is the summer suspense novel that readers will remember in September. It is a book about two women, both smart, both compromised, both loved, both surviving. It is a book about a husband whose wife’s certainty about him is the novel’s most quietly devastating character. It is a book that Katie Couric’s readers will hand to their friends, and that their friends will finish in a weekend and text them about at midnight.

McCreight has written her most complete novel. The audience she has spent twenty years earning has arrived to meet it.

SOMEONE ELSE’S HUSBAND by Kimberly McCreight is available in hardcover, ebook, and audiobook wherever books are sold.
