Oprah Winfrey is ready to move on from American Dirt. The media maven announced the newest pick for her popular book club on Tuesday: Robert Kolker’s Hidden Valley Road: Inside the Mind of an American Family.

“This is a riveting true story of an American family that reads like a medical detective journey,” Winfrey said. “It reveals the shame, denial, shock, confusion, and misunderstanding of mental illness at a time when no one was really sure what schizophrenia was or how to treat it.”

Kolker’s nonfiction book, which was published on Tuesday, follows the Galvin family, a married mid-20th-century couple with 12 children, six of whom would eventually be diagnosed with schizophrenia. A reviewer for Kirkus called the book “a family portrait of astounding depth and empathy.”

“Anybody who has had mental illness of any kind in their family, or knows somebody who’s mentally ill, you’ll get so much information,” Winfrey said in a video posted on her website.

Hidden Valley Road is Winfrey’s first book club selection since Jeanine Cummins’ American Dirt, the immigration-themed novel that set off a firestorm of controversy because of what some critics considered stereotyping and cultural appropriation in the book. It’s also the first nonfiction book Winfrey has tapped for her club since Michelle Obama’s Becoming, one of her picks from last year.

On Twitter, Kolker didn’t seem quite ready to discuss being anointed by Oprah.

“I’ll be glad to talk rationally about this once I GET UP OFF THE FLOOR,” he tweeted.
