If you’ve somehow managed to avoid The Love Hypothesis during the BookTok takeover, Amazon is making it pretty easy to finally see what all the fuss is about. Ali Hazelwood’s wildly popular romance novel is currently available for just $8.97 on Amazon, bringing the paperback below the $9 mark.

The Love Hypothesis follows Olive Smith, a third-year Ph.D. candidate who finds herself in a fake-dating arrangement with Adam Carlsen, a notoriously intimidating professor. What starts as a convenient academic charade predictably gets complicated when the fake relationship starts feeling considerably less fake.

The book became a major BookTok hit after its 2021 release, with reporting at the time describing it as a smash BookTok success. Penguin Random House also describes it as an instant #1 New York Times bestseller and a TikTok sensation.

There’s also a timely reason to pick it up now: the movie adaptation of The Love Hypothesis is already streaming on Prime Video, having premiered on September 23, 2026. So if you’ve watched the movie and want to revisit the original story — or you’d rather read the book before watching it — Amazon’s sub-$9 price makes the paperback an easy addition to your reading list.

At $8.97, this is an easy price point for anyone who has had The Love Hypothesis sitting on their BookTok-induced reading list forever. Amazon lists the paperback as available for purchase.
