Last Updated on November 28, 2023 by Louisa

If you’re in the mood for a sweet, tender, and gripping romance novel, then it’s no surprise you’re looking for books like The Love Hypothesis.

In fact, I even got asexual vibes from our protagonist Olive, which is two thumbs up from Epic Book Society!

The Love Hypothesis delivers this effortlessly.
