'The Love Hypothesis' Officially Sets Sequel Release Date

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.

Hazelwood has officially announced The Two-Body Problem, a direct sequel to her bestselling romance novel The Love Hypothesis. The new book will be released on February 2, 2027, and returns to Adam and Olive several years into their relationship. And things are moving extremely quickly beyond the page, too. 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.

Announcing the novel, Hazelwood admitted that writing a sequel wasn't something she had planned even relatively recently. Instead, working on the movie adaptation helped her fall in love with Adam and Olive all over again.

“‘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 continued:

“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.”

What Is 'The Two-Body Problem' About?

Hazelwood says the sequel will span a couple of years in Adam and Olive's lives rather than simply attempting to recreate the setup that made The Love Hypothesis such a hit. The story will mix everyday life with postdoctoral turmoil and the realities of maintaining a long-term relationship.

And, naturally, there will be one challenge more terrifying than anything academia can throw at them.

“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 also acknowledged that some readers might prefer leaving Adam and Olive exactly where the original novel left them. Describing herself as someone who becomes “VERY attached to stories and characters,” she encouraged anyone who doesn't want a sequel to simply keep their own version of what happened next.

The announcement comes just days after The Love Hypothesis director Claire Scanlon was asked about the possibility of continuing Adam and Olive's story. Her answer suddenly looks considerably less evasive than it did at the time.

“I think that's a great question for Ali Hazelwood. I think she might have an answer for you. She's the creative genius behind all of this.”

Scanlon insisted that fans knew as much as she did, but rather pointedly suggested taking the question directly to Hazelwood, which now seems rather sneaky:

“You know as much as I know, but I would say follow through and get yourself over in front of Ali and ask the question. I have to say, just like I love making solid comedies, and if there's romance in them, great.”

The Two-Body Problem will be released on February 2, 2027. MRC is currently developing a film adaptation for Amazon MGM Studios.
