Ware is often compared to Agatha Christie, and she’s stated that Christie’s influence has had a major impact on her writing style. Like Christie, many of Ware’s novels place characters in dangerous, inescapable situations, often leading them to question their sanity. Ware’s works have been celebrated by many; she won the NPR best book of 2015 award for In a Dark, Dark Wood and was shortlisted for the Ian Fleming Steel Dagger Award for her novel One by One.

Fans of Michaelides also love his 2021 novel, The Maidens, a psychological crime thriller that delves into murders on college campuses in England. His 2024 release The Fury has been praised as his most ambitious work yet, featuring multiple unreliable narrators and a locked-room mystery that keeps readers guessing until the final page.

What makes Michaelides particularly appealing to Riley Sager fans is his background in screenwriting, which brings a cinematic quality to his thrillers. Each chapter feels like a carefully crafted scene, building tension methodically toward explosive revelations.

“We are made up of different parts, some good, some bad, and a healthy mind can tolerate this ambivalence and juggle both good and bad at the same time. Mental illness is precisely about a lack of this kind of integration - we end up losing contact with the unacceptable parts of ourselves.”

His recent novels have shown a shift toward more psychological horror, making them particularly appealing to Riley Sager enthusiasts.

Inspired by writers including Mary Shelley, Bram Stoker, and Nathaniel Hawthorne, readers love how King writes as if speaking directly to his reader. When asked why he became a writer, King stated, “The answer to that is fairly simple—there was nothing else I was made to do. I was made to write stories, and I love to write stories. That’s why I do it. I really can’t imagine doing anything else, and I can’t imagine not doing what I do.”

“The thing under my bed waiting to grab my ankle isn’t real. I know that, and I also know that if I’m careful to keep my foot under the covers, it will never be able to grab my ankle.”

Foley’s recent 2024 release has cemented her reputation as a master of the multi-perspective thriller. Her 2025 upcoming novel promises to be her most ambitious yet, featuring an ensemble cast trapped in an isolated location—a setup that Riley Sager fans will find irresistible.

Her style forces readers to pay close attention—between multiple points of view and a perfectly paced storyline, readers find that they lose track of the hours when they’re digging into one of Foley’s novels.

For 2025, Kubica has announced a new standalone thriller that promises to explore themes of identity and memory—perfect territory for Riley Sager fans.

Her exploration of how ordinary people react under extraordinary pressure mirrors the psychological complexity that makes Riley Sager’s work so compelling.

8. Rachel Hawkins

Rachel Hawkins is best known for her NYT bestselling series Hex Hall and her thriller, Reckless Girls. With more than a dozen novels under her belt, Hawkins is also known for her work under the pen name Erin Sterling, under which she writes paranormal romance thrillers like 2021’s The Ex Hex (which was named both an NYT and USA Today bestseller).

Hawkins’ 2024 thriller The Divorcée marked a significant shift toward darker psychological territory, earning comparisons to Riley Sager for its exploration of how well we really know the people closest to us. Her upcoming 2025 release promises to continue this evolution toward more psychologically complex narratives.

If you love Agatha Christie’s style, you’ll likely also be a Hawkins fan, as she masterfully combines classic mystery elements with contemporary psychological thriller pacing.

“It sucks that we miss people like that. You think you’ve accepted that someone is out of your life, that you’ve grieved and it’s over, and then bam. One little thing, and you feel like you’ve lost that person all over again.”

• Rachel Hawkins, Demonglass

9. Simone St. James

Simone St. James is a Canadian mystery and thriller author. Before pursuing writing as a full-time career, St. James spent two decades working in television. Like many authors, she was drawn to writing because the books she wanted to read—goosebump-inducing ghost stories without gore, plus romance—were impossible to find.

St. James has carved out a unique niche in 2025 by blending historical settings with supernatural psychological thrillers. Her latest releases have been praised for their atmospheric tension and the way she uses paranormal elements to heighten psychological suspense rather than rely on them as plot devices.

Many of St. James’ books are historical fiction set in the 1920s and 1950s. Some of her novels, like The Book of Cold Cases, jump between two timelines, allowing readers to experience multiple perspectives and see how a storyline changes over time. This temporal complexity will appeal to Riley Sager fans who enjoy narratives that reveal information gradually.

“The person who could be truly alone, in the company of no one but oneself and one’s own thoughts—that person was stronger than anyone else. More ready. More prepared.”

• Simone St. James, The Sun Down Motel

10. Ella Drummond

Ella Drummond is a psychological thriller author known for fast-paced books with unexpected twists and turns. Her 2019 novel, My Last Lie, takes readers on the journey of Theo and Pilar, a seemingly perfect couple who work through an unthinkable tragedy and are forced to tell each other their secret truths once and for all.

While Drummond may be less well-known than some authors on this list, her work has gained significant traction in 2024 and 2025 through word-of-mouth recommendations and social media buzz. Her latest releases have shown remarkable growth in psychological complexity and narrative sophistication.

Fans of Drummond’s work love how she makes her characters human, writing a balance of likable and unlikeable traits. Readers question whether they should root for Drummond’s protagonists, as their flaws and mistakes can make it tough to be on their side. This moral ambiguity is a hallmark of the best psychological thrillers and makes her work particularly appealing to Riley Sager fans.

“I didn’t add that I’d always intended to move into the house he bought, whatever it looked like. I didn’t think I had the right to be too choosy about anything. My only insistence had been that it was somewhere new, far away from our previous life.”

• Ella Drummond, My Last Lie
