Ruth Ware books are not all created equal, and I say that as someone who has read seven of them. Ruth Warburton published five young-adult fantasy novels under her birth name before switching to crime fiction under the pen name Ruth Ware in 2015. All ten of her thrillers have debuted on the New York Times bestseller list, and her books have sold more than ten million copies across more than 40 languages. Of the seven I have read, one stands apart: The Turn of the Key earned five stars. Here is my honest ranking of all seven. (The Lying Game, The Death of Mrs. Westaway, and The Woman in Suite 11 I have not gotten to yet.)
The Turn of the Key by Ruth Ware
The Turn of the Key (Gallery/Scout Press, August 2019) follows Rowan Caine, who writes to a lawyer from prison, detailing her nannying post at Heatherbrae House — a tech-controlled smart home in the Scottish Highlands — that ended in a child’s death and her arrest for murder. She insists she did not do it. Ruth Ware drew the premise from Henry James’s The Turn of the Screw (1898), updating the Victorian governess-in-a-haunted-house template to a smart home where doors lock remotely, cameras watch every room, and voice-activated speakers respond to sounds they should not. The epistolary structure (the entire novel is Rowan’s letter to the lawyer she is begging to take her case) means you know from the opening page that something terrible happened. The question is what, and who actually did it.
This one is for you if you want Ruth Ware at her most inventive and a thriller where the structure itself is part of the suspense. Find The Turn of the Key on Goodreads.
In a Dark, Dark Wood by Ruth Ware
In a Dark, Dark Wood (Gallery Books, August 2015) opens with crime writer Nora waking in a hospital with no memory of what happened, then pulls back to the hen party weekend in a remote English forest where it all went wrong. Ruth Ware’s debut was an NPR Best Book of the Year and a New York Times bestseller. The amnesiac structure — knowing something happened before the story starts, not what — generates tension from the first page without requiring graphic content. The fear is atmospheric, the remote forest setting is a classic closed circle, and the small group of guests all have secrets. It is also the most beginner-friendly entry in her catalog, which is why it appears in my list of best thriller books for beginners.
This one is for you if you want to start with Ruth Ware and like the idea of a thriller set over one intense weekend. Find In a Dark, Dark Wood on Goodreads.
The Woman in Cabin 10 by Ruth Ware
The Woman in Cabin 10 (Scout Press, July 2016) follows Lo Blacklock, a travel journalist on an exclusive press trip aboard a luxury cruise ship, who hears what sounds like a woman being thrown overboard from the cabin next door. The ship’s manifest shows no passenger in that cabin. No one believes her. Ruth Ware’s novel became a New York Times bestseller, sold more than two million copies, and was published in more than 40 countries. The wealth-and-glamour setting does something her forest and countryside locations cannot: it makes the escalating dread feel dissonant rather than expected, which sharpens it. Lo Blacklock returns in The Woman in Suite 11 (Scout Press, 2025) for readers who want more from the character after this one.
This one is for you if you want her most commercially successful novel and a thriller where the luxury setting is part of the trap. Find The Woman in Cabin 10 on Goodreads.
The It Girl by Ruth Ware
The It Girl (Scout Press, July 2022) follows Hannah, who arrived at Oxford and found April Clarke-Cliveden — the most magnetic person on campus — as her first friend. By the end of their second year, April was dead and Hannah’s testimony had sent a man to prison for it. Ten years later, that man dies in prison, and a journalist arrives with evidence that he may have been innocent. Ruth Ware’s novel was nominated for the Goodreads Choice Award for Best Mystery & Thriller in 2022 and became a New York Times bestseller. The friendship between Hannah and April is the emotional core of the book, not merely a device to set up the crime, and the Oxford setting feeds the investigation with class dynamics and institutional secrets that make the whodunnit feel earned.
This one is for you if you want her strongest character work and a cold-case mystery where the friendship matters as much as the murder. Find The It Girl on Goodreads.
One by One by Ruth Ware
One by One (Scout Press, September 2020) follows eight coworkers from a London tech startup stranded at a ski chalet in the French Alps after an avalanche cuts off the road out. As rescuers cannot reach them and supplies dwindle, people start dying. Ruth Ware’s novel became a New York Times bestseller. It is her most Agatha Christie-adjacent book: a closed circle, an ensemble cast where everyone is a suspect, and a motive layered into the corporate politics of an acquisition vote that every person in the chalet has a stake in. Read it after you have tried one or two others in her catalog rather than as an entry point.
This one is for you if you want a closed-circle mystery with corporate stakes underneath it. Find One by One on Goodreads.
Zero Days by Ruth Ware
Zero Days (Scout Press, June 2023) follows Jack Cross, a professional penetration tester who returns home from a job one night to find her husband murdered. She becomes the prime suspect and goes on the run, using her security expertise to evade capture while investigating the killing. Ruth Ware’s novel became a New York Times bestseller. I did not record a rating for this one on Goodreads, which reflects my mixed response: it is her most different novel. The penetration testing premise gives it a procedural, action-driven texture that is not the atmospheric Gothic mode her best work operates in. Whether that is a problem depends entirely on what you are looking for.
This one is for you if you want a Ruth Ware novel built around action and procedure rather than psychological dread. Find Zero Days on Goodreads.
One Perfect Couple by Ruth Ware
One Perfect Couple (Scout Press, May 2024) follows Lyla, who agrees to join a reality TV competition called One Perfect Couple with her boyfriend Nico — five couples on a remote Indonesian island competing for a cash prize. The production crew leaves with all the electronics and does not return. The couples realize they have been abandoned with limited food, no communication, and someone among them who intends to be the last one standing. Ruth Ware’s novel became a New York Times bestseller. The formula that makes her best work tense — confined spaces, Gothic atmosphere, class dynamics in close quarters — does not survive the transplant to a tropical island and a reality TV premise. This is the honest low of my seven reads.
This one is for you if you want a Ruth Ware novel that leans toward survival thriller rather than psychological suspense. Find One Perfect Couple on Goodreads.
If you are new to Ruth Ware, start with In a Dark, Dark Wood rather than the top of this list. The Turn of the Key is the better novel. In a Dark, Dark Wood is the better entry point. I have not yet read The Lying Game, The Death of Mrs. Westaway, or The Woman in Suite 11, so this ranking covers the seven I have. For more atmospheric thriller recommendations, my ranking of best Riley Sager books is a natural next stop. Find me on Instagram and Goodreads — I would love to know which one you read first.
