Books Written by Robert Kolker

Robert Kolker writes about families who have been handed something nobody knows how to carry. A serial killer's victims, reported as the people they were rather than as a case. Twelve children in Colorado, six of whom developed schizophrenia. A family losing itself to a rare inherited dementia. He is a magazine journalist by training, and his books read like it: years of interviews, no invented scenes, and the science and the grief given equal weight. He has written three books, and this guide covers all of them in order.

Where to Start with Robert Kolker

If you read only one
Hidden Valley Road (2020).

If you came for the true crime
Lost Girls (2013), knowing it is about the victims rather than the killer.

If dementia is close to home
The Vanishing Family (2026), and take your time with it.

If you would rather watch first
Lost Girls on Netflix (2020), then read the book, which goes much further.

Lost Girls

An Unsolved American Mystery

Robert Kolker · 2013

Five young women who advertised as escorts on Craigslist went missing between 2007 and 2010; their bodies were found in the marsh grass along Gilgo Beach on Long Island. Kolker gives each of them a life before the case: where they came from, why they did the work, the families who kept looking after the police stopped. When the book appeared the killer had not been caught, and TIME later named it one of the best true crime books ever written. Liz Garbus filmed it for Netflix in 2020, with Amy Ryan as one of the mothers.

Read it for what it refuses to do. There is no thrill here, no puzzle-solving, just five women restored to being people. It is the book I would hand to anyone who says they do not like true crime.

Inside the Mind of an American Family

Robert Kolker · 2020

Don and Mimi Galvin had twelve children in Colorado between 1945 and 1965. Six of the boys developed schizophrenia. Kolker tells the family's story alongside the history of how the illness has been understood and misunderstood, and the genetic research the Galvins themselves made possible. The two youngest sisters approached him to write it. Published on April 7, 2020, it went straight to number one on the New York Times list, was chosen for Oprah's Book Club, and was one of Barack Obama's favourite books of that year.

Start here. It holds two books at once, a family saga and a history of psychiatry, without letting either flatten the other.

Love, Fate, and the Quest to End Dementia

Robert Kolker · 2026

His third book, published on September 29, 2026. It follows one family living with an inherited form of dementia, where each sibling has a fifty-fifty chance of carrying the gene, and the scientists working towards a treatment. The structure is the one he used in Hidden Valley Road: a family saga braided with a medical detective story. The New York Times listed it among the nonfiction books everyone would be talking about in 2026.

If Hidden Valley Road worked on you, this is the same method turned on a different illness.

What to Expect from a Robert Kolker Book

All three follow the same method, which is worth knowing before you pick one up.

  • One family, closely reported — years of interviews with the people involved, told without invented scenes or imagined dialogue. Read the entries →
  • The science alongside the story — the history of how an illness was understood, or how a case was investigated, braided into the family's chapters.
  • The people first — in Lost Girls that means the five women rather than the man who killed them. There is no lurid detail and no puzzle to solve.
  • Difficult subjects — murder, schizophrenia and inherited dementia. He handles them carefully, but they are not light reading. Read the entry →

In What Order to Read Robert Kolker

The books are unconnected, so read them in whatever order the subject pulls you. Publication order does show his method developing: Lost Girls is reported journalism, and the two later books add the science and the family history around it.

How Robert Kolker Writes: The Family Is the Story

Kolker came to books from magazines, and it shows in the reporting rather than in the prose. He spends years with the people he writes about, and he does not invent: no reconstructed dialogue, no imagined interior monologue, no scenes he was not told about. When something is unknown, the book says so. That restraint is why families who have been badly served by the press seem willing to talk to him.

The structure is consistent across all three books. A family carries the narrative, and the history of the thing that happened to them, a criminal investigation, a century of psychiatry, a hunt for a genetic cause, runs alongside it. Neither swamps the other. In Hidden Valley Road that means the Galvins' story is also a history of how schizophrenia has been explained, including the decades in which mothers were blamed for it.

What is unusual is where he puts his sympathy. Lost Girls was published while the Gilgo Beach case was unsolved, and Kolker used that space to write about the five women as daughters, sisters and mothers rather than as victims of an unnamed man. Reviewers noticed that the book barely speculates about the killer at all. That was a deliberate choice, and it is the reason the book has lasted.

Frequently asked questions about Robert Kolker's books

How many books has Robert Kolker written?

Three: Lost Girls: An Unsolved American Mystery (2013), Hidden Valley Road: Inside the Mind of an American Family (2020) and The Vanishing Family: Love, Fate, and the Quest to End Dementia (2026). All three are narrative nonfiction.

What are Robert Kolker's books in order?

In order of publication: Lost Girls (2013), Hidden Valley Road (2020), The Vanishing Family (2026).

Which Robert Kolker book should I read first?

Hidden Valley Road (2020). It is his best-known book, a number one New York Times bestseller and an Oprah's Book Club pick, and it shows his method at full stretch: a family story and a history of psychiatry told together.

What is Hidden Valley Road about?

It is the story of the Galvin family of Colorado Springs, who had twelve children between 1945 and 1965, six of whom developed schizophrenia. Kolker tells their story alongside the history of how the illness has been understood, and the genetic research that the family's DNA helped make possible. The two youngest sisters approached him to write it.

What is Lost Girls about?

Lost Girls (2013) is about five young women who advertised as escorts online and disappeared between 2007 and 2010, whose bodies were later found along Gilgo Beach on Long Island. Rather than focusing on the unidentified killer, Kolker reconstructs each woman's life and follows the families who kept pressing the police for answers.

Has the Gilgo Beach case been solved?

Not when the book was published in 2013. In July 2023, Rex Heuermann, an architect from Massapequa Park, was arrested and has since been charged with the murders of seven women connected to the case. He has pleaded not guilty, and proceedings have continued since. For the current state of the case, check a recent news source rather than the book.

Is Lost Girls a movie?

Yes. Netflix released Lost Girls in 2020, directed by Liz Garbus, with Amy Ryan as Mari Gilbert, the mother of one of the missing women. The film covers roughly the first part of the book; the book goes considerably further into all five women's lives.

What is Robert Kolker's newest book?

The Vanishing Family: Love, Fate, and the Quest to End Dementia, published by Doubleday on September 29, 2026. It follows a family living with an inherited form of dementia and the scientists searching for a treatment.

Is Hidden Valley Road a true story?

Yes. The Galvins are a real family, and Kolker reported the book over several years, interviewing surviving siblings and their mother, Mimi Galvin, and drawing on medical records and the research studies the family took part in.

Who is Robert Kolker?

Robert Kolker is an American journalist and author, born in Baltimore and educated at Columbia University. He is a contributing writer at The New York Times Magazine, and was previously a contributing editor at New York magazine and an investigations reporter at Bloomberg. He is a National Magazine Award finalist and won the Harry Frank Guggenheim Award for criminal justice reporting in 2011.

Did Robert Kolker write Bad Education?

He wrote the article it came from. His 2004 piece for New York magazine, “The Bad Superintendent”, about an embezzlement scandal in a Long Island school district, became the HBO film Bad Education (2020), starring Hugh Jackman and Allison Janney.

Are Robert Kolker's books hard to read?

They deal with murder, schizophrenia and inherited dementia, so they ask something of you emotionally. What makes them bearable is his restraint: there is no lurid detail, no speculation about suffering, and the people involved are treated as people rather than as material. If the subject is close to your own life, take them slowly.
