The Two-Body Problem

The Love Hypothesis #2

by Ali Hazelwood

The highly anticipated sequel to the instant New York Times and global bestselling phenomenon, The Love Hypothesis.

Olive Smith finally has her PhD, and she's living her happy ever after. Well, not quite hereverafter, since postdoctoral fellowships are temporary by nature, but she doesn't mind: she has her friends, her research, and best of all, she has Dr. Adam Carlsen. Intense, brilliant, endlessly undaunted by the chaos Olive has smuggled into their shared house, Adam is determined to spend his future by her side.

And yet, there are no fairy tales in academia. Being in love with another researcher means navigating the hard reality of clashing schedules, an increasingly grim and ultracompetitive job market, and Olive's desire to be seen as a formidable scientist in her own right.

Being with Adam is the most real thing Olive has ever known. As the pressure tightens and the stakes rise, she'll have to set all confounding variables aside and learn to trust her heart.

About the author

I'm Ali, and I write contemporary romcom novels about women in STEM and academia. I love cats, Nutella, and side ponytails. I'm also currently learning to crochet, so as you can tell I'm a super busy gal with an intense and exciting life!

I only use Goodreads as a reader, to review and hype books that I've loved (many of these book are ARCs received from fellow authors).

Reviews

[Clace]

Not to sound like the biggest bitch- but why is she writing a sequel to a book with a perfect ending 😭 I liked that we got snippets of them in other books but cmon now 😭 this is literally for the sake of having another adaptation.

[levi (starboy) (s.ia)]

[Liana Gold]

Mark your calendar friends! I haven't even read/watched the first movie.. yet I'm already excited for the sequel ;)

[aira]

I thought the movie was actually good (I prefer the movie to the book), but maybe I’ll like the sequel more lol 🤣

[rei ‧₊˚✩彡]

[Dab]

I hope they exhausted their limit of miscommunication and third-act breakups in the first book. In any case, I can’t wait 🥰🥰🥰

[Salma (inactive)]

OMG OMG OMG YESSSS I WANNA SCREAM. MORE ADAM. MORE YEARNING.

PLEASE LET THIS BE GOOD

[EM]

ARE MY EYES PLAYING TRICKS ON ME?!?!

WDYM WE’RE GETTING A SEQUEL TO THE LOVE HYPOTHESIS?! And more importantly… WDYM WE GET MORE ADAM CARLSEN AGAIN?! 😭

I'm genuinely not prepared for this announcement. Like, excuse me??? You cannot just casually drop Adam Carlsen back into my life and expect me to act normal about it.

I thought I had made peace with having only one book of Adam. Apparently Ali Hazelwood said, absolutely not.
THE ADAM CARLSEN. No synopsis needed. No reviews needed. No questions asked. Just take my money.

[Ri ♡]

I guess at the end it's always about money 🤡 i love adam and olive so much but i am sorry i don't want her to create unnecessary conflicts between them when they clearly have a HEA and just because ali wants to make more money in 2026. I love her books but please stop this nonsense of writing unnecessary sequels

[julie ★ (new bio !)]

WHAT THE FUCK. OMG

[mary ♡⋆ ࣪₊ꫂ᭪݁⋆˙]

WAKE UP BESTIES WE ARE GETTING A SEQUEL AAAAA

[Freefall (super inactive rn sorry)]

is no one going to talk about the title referencing the three-body problem by liu cixin? kinda surprised she even knows what that is tbh but i'm just an ali hazelwood hater

[jasmine ☆₊⁺🦢🪽₊⁺★]

AHHH STOPP!! I KNOW YOU’RE LYING

[Dahlia]

Not gonna lie am really exited to see how this one is going to be even if i wasnt a fan of the movie it was okay but they brushed off so so many important and amazing scenes and I know its just how movies are but still 🥺💔
Anyways the love hypothesis (the book i hate how i have to clarify it now lol) was chefs kiss so I swear if they ruin Dr.Evil and Olive for me am done .. 🙂 (begging at this rate)

[lea ⊹ ࣪ ˖ (busy)]
