The sequel, set a couple of years after the original, explores the challenges faced by the characters Olive and Adam as they navigate their relationship and professional lives.
Hazelwood described the book as a mix of slice-of-life moments, postdoctoral turmoil, and the realities of being in a long-term relationship, including the 'hardest challenge one will face in a long-term relationship: deciding what to have for dinner.
MRC, which produced the film adaptation of 'The Love Hypothesis,' is developing a movie adaptation of 'The Two-Body Problem' for Amazon MGM Studios.

While the sequel's release date has not been officially announced, Hazelwood expressed eagerness to discuss the book further in the coming months.
Amazon MGM Studios has not yet revealed casting details for the sequel film, though it is likely that the original cast will be considered for reprisal roles.
Filming for the sequel has not yet begun, and no trailer is currently available.
What this adds
The sequel's development and release date are still in the planning stages, with no official announcement from Amazon MGM Studios regarding casting or production timelines.
Background
The Love Hypothesis is a romance novel by Ali Hazelwood, published September 14, 2021 by Berkley Books. Originally published online in 2018 as Head Over Feet, a Star Wars fan fiction work about the "Reylo" ship between Rey and Kylo Ren, the novel follows a Ph.D. candidate and a professor at Stanford University who pretend to be in a relationship.
What's confirmed
- “‘I wrote a sequel to The Love Hypothesis’ is not a sentence I thought I’d say a year or so ago, but now I weirdly can’t imagine a world in which The Two-Body Problem doesn’t exist. I’m really eager to talk more about this book and how it came about in the next few months,” Hazelwood wrote.
- “If you want to read more about Adam and Olive, The Two-Body Problem spans a couple of years, and it’s a mix of slice of life, postdoctoral turmoil, and unflinching exploration of the hardest challenge one will face in a long-term relationship: deciding what to have for dinner. If you pick it up, I really hope you enjoy,” Hazelwood wrote.
- “For now let me just say that the TLH movie and its cast made me fall for Adam and Olive all over again, that revisiting them was an absolute pleasure.” The announcement comes amid the recent release of The Love Hypothesis film adaptation.
- MRC is already developing a movie adaptation of The Two-Body Problem for Amazon MGM Studios, although Hazelwood cautioned that “nothing is guaranteed” at this stage.
What's still developing
- Through their time together, “each of their carefully calculated theories on love are thrown into chaos,” according to an official description from Amazon MGM Studios.
- Icebreaker was acquired by Atria Books, an imprint of Simon & Schuster, for a wider November 2022 release after its self-published debut caught fire online.
- Grace herself announced the news on Instagram with a response that was perfectly, simply to the point: “I’m truly the luckiest girl in the world.” Hannah Grace is an English author based in Manchester, and her journey from corporate employee to number one New York Times bestselling novelist is one of the most satisfying in recent romance publishing.

- The project is still in development, so filming details likely won't be confirmed until a script is locked in and production dates are set.
- Apparently, Ali Hazelwood wasn't quite finished with Adam and Olive after all.
- The Love Hypothesis has already made the leap from BookTok phenomenon to upcoming movie, but returning to those characters on set has now produced something even more unexpected: an entire sequel that Hazelwood herself didn't think she'd ever write.
- Announcing the novel, Hazelwood admitted that writing a sequel wasn't something she had planned even relatively recently.
- The author admitted that writing a sequel wasn’t originally part of the plan.
- The book follows Olive as she navigates the “hard reality of clashing schedules, an increasingly grim and ultra-competitive job market,” and her own “desire to be seen as a formidable scientist in her own right” all while being in love with fellow researcher, Dr. Adam Carlsen, according to a synopsis.
