In Riley Sager's own words

Riley Sager speaks with Olivia Fierro about the inspiration, gothic atmosphere, and 1980s setting of his thriller 'The Only One Left'.

Learning to appreciate fast readers

Sager says he initially felt defensive when readers told him they finished his books in a single afternoon after he spent ten months writing them, but he now appreciates it as a high compliment.

Hesitation about adapting his own work

Sager says that although he loves movies, he is skeptical about adapting his own novels because scriptwriting requires cutting beloved scenes and making painful compromises.

Ask LuvemBooks about Riley Sager

Riley Sager — the pen name of American thriller writer Todd Ritter — specializes in Gothic-tinged thrillers where a woman returns to or enters an ominous house and confronts an old crime, as in The Only One Left, which sends caregiver Kit into a Maine mansion to tend a woman long accused of a Lizzie Borden-style family massacre. We've reviewed 2 of their books, both New York Times bestsellers built on twist-heavy structures; The Only One Left holds a 4.4/5 reader rating from over 63,000 Amazon ratings, while Home Before Dark pairs a skeptical daughter with the haunted history of a Victorian estate through a dual-narrative structure critics praised.
Where should I start?
Start with The Only One Left — it carries the highest reader rating of the books we've reviewed at 4.4/5 from over 63,000 Amazon ratings, and its setup is a strong showcase of Sager's style: caregiver Kit arrives at a Maine mansion to care for Lenora Hope, who was accused decades earlier of murdering her family in a Lizzie Borden-style massacre. If you prefer a more supernatural edge, Home Before Dark is the alternative entry point.
What's their writing style?
Sager writes Gothic-flavored thrillers built around women confronting dark secrets in imposing houses — a Maine mansion in The Only One Left, the Victorian Baneberry Hall in Home Before Dark. Their books favor relentless pacing and twist-driven plotting; Home Before Dark was praised for its ingenious dual-narrative structure, while some critics feel the twists in The Only One Left strain believability.
Books we've reviewed
We've reviewed 2 Riley Sager books. The Only One Left (4.4/5 reader rating from over 63,000 Amazon ratings) follows caregiver Kit into a Maine mansion where her patient stands accused of a decades-old family massacre. Home Before Dark (4.3/5 reader rating from nearly 29,000 Amazon ratings) is a psychological horror novel pitting a skeptical daughter against the secrets of Baneberry Hall, told through an acclaimed dual-narrative structure.
How do their books compare?
Both books we've reviewed share Sager's signature setup of a woman facing the sinister history of a grand old house, but they differ in flavor. The Only One Left is a Gothic murder mystery — Kit caring for accused killer Lenora Hope — while Home Before Dark tips into psychological horror as a skeptical daughter confronts Baneberry Hall's secrets. Home Before Dark drew stronger critical praise for its dual-narrative structure, though The Only One Left has the slightly higher reader rating (4.4 vs 4.3).
Why is The Only One Left trending?
The Only One Left is currently trending among Sager's books. It's an instant New York Times bestseller with a 4.4/5 reader rating from over 63,000 Amazon ratings — one of the largest rating counts we track — built on an irresistible premise: a caregiver tending an elderly woman accused of a notorious family massacre decades earlier.
What genre do they write?
Riley Sager writes thrillers — specifically, thrillers with a strong Gothic atmosphere and, in Home Before Dark's case, outright psychological horror. Their books typically center on women investigating dark pasts tied to menacing old houses.
What should I read after The Only One Left?
Home Before Dark is the natural next stop among the Sager books we've reviewed. It keeps the ominous-house formula — this time the Victorian Baneberry Hall — but shifts toward psychological horror with a dual-narrative structure that earned strong critical praise. It holds a 4.3/5 reader rating from nearly 29,000 Amazon ratings.
