Based on the available information and the data hitherto collected, my hypothesis is that the further I stay away from love, the better off I will be.
'Contemporary romance's unicorn: the elusive marriage of deeply brainy and delightfully escapist.' Christina Lauren, New York Times bestselling author of The Unhoneymooners
*
When a fake relationship between scientists meets the irresistible force of attraction, it throws one woman's carefully calculated theories on love into chaos.
As a third-year Ph.D. candidate, Olive Smith doesn't believe in lasting romantic relationships but her best friend does, and that's what got her into this situation. Convincing Anh that Olive on her way to a happily ever after was always going to be tough, scientists require proof. So, like any self-respecting woman, Olive panics and kisses the first man she sees.
That man is none other than Adam Carlsen, a young hotshot professor and well-known ass. Which is why Olive is positively floored when he agrees to keep her charade a secret and be her fake boyfriend. But when a big science conference goes haywire and Adam surprises her again with his unyielding support (and his unyielding abs), their little experiment feels dangerously close to combustion.
Olive soon discovers that the only thing more complicated than a hypothesis on love is putting her own heart under the microscope.
What the five star reviews are saying about The Love Hypothesis:
'Did I read this in 24 hours? Yes.'
'Funny. Snarky. Intelligent. Real.'
'If you're even slightly thinking about getting this book to read, just go a head and do it'
'Adam is just *swoon*'
'Ali Hazelwood has made herself an auto-buy author'
'It was just... perfect.'
'A heroine you will instantly fall in love with'

Ali Hazelwood is a multi-published author - alas, of peer-reviewed articles about brain science, in which no one makes out and the ever after is not always happy. Originally from Italy, she lived in Germany and Japan before moving to the US to pursue a Ph.D. in neuroscience. She recently became a professor, which absolutely terrifies her. When Ali is not at work, she can be found running, crocheting, eating cake pops, or watching sci-fi movies with her two feline overlords (and her slightly-less-feline husband).

Review
Contemporary romance's unicorn: the elusive marriage of deeply brainy and delightfully escapist...The Love Hypothesis has wild commercial appeal but the quieter secret is that there is a specific audience, made up of all of the Olives in the world, who have deeply, ardently waited for this exact book.
-- Christina Lauren, New York Times bestselling author of The UnhoneymoonersFunny, sexy and smart.
-- Mariana Zapata, New York Times bestselling authorThis tackles one of my favorite tropes - Grumpy meets Sunshine - in a fun and utterly endearing way... I loved the nods towards fandom and romance novels, and I couldn't put it down. Highly recommended!
-- Jessica Clare, New York Times bestselling authorPure slow-burning gold with lots of chemistry.
― PopsugarSmart, witty dialogue and a diverse cast of likeable secondary characters... A realistic, amusing novel that readers won't be able to put down. ― Library Journal, starred review
With whip-smart and endearing characters, snappy prose, and a quirky take on a favourite trope, Hazelwood convincingly navigates the fraught shoals of academia... This smart, sexy contemporary should delight a wide swathe of romance lovers. ― Publishers Weekly
When a book has a certain type of magic between the pages, you manage to get from the prologue to the epilogue without coming up for air ... The Love Hypothesis was one of these books.

Ok ok ok, so was The Love Hypothesis a new favourite? Sadly not. I found the first 11 chapters a bit of a slog to be quite honest. The fake PDA moments made me cringe and also, I have a burning question - why did Olive keep expecting Adam to buy her coffees? I didn't get that at all. So yeah over half was a bit meh for me, I didn't understand the hype at all.
Its no spoiler the route this book was going to take, lets be honest. So when the inevitable happened.... well Ali Hazelwood can write a good smutty scene, let me tell you! When feelings were finally revealed, I ended up enjoying this book a lot more. I found both characters likeable (had a bit of a crush on Adam tbh) and enjoyed their chemistry.
It wasn't a new favourite and took a while to get going, yet in the end I did enjoy it buuuuuuuuuuuut (and I'm sorry) I think it has been overhyped. Like it was ok, however I have read much better romances.
Olive found herself in a difficult situation, her best friend is attracted to her ex and while she has no problem with them dating, her friend thinks she isn't over him. Which naturally leads to Olive kissing a stranger in the university in order to convince her that she is dating someone else.
Adam, is the serious professor that many grad students are afraid of, he doesn't seem like the ideal candidate as a fake boyfriend but he agrees as this arrangement it will benefit him as well.
The first scene might be the most memorable first scene I have read, it starts with a bang, or more accurately with a kiss, and it only gets better from there.
The fake dating trope is one of my favourites and especially when Olive makes witty comments about it as a trope in the book. “It doesn’t matter what it says. It’s always one bed.” "Or a poorly written young adult novel. That will not sell well."
The book is unique and fun. I found the writing very clever and refreshing.
Adam was especially loveable, he was devoted and incredible sweet. Olive is very smart and I like that she was a good friend.
The romance was wonderful, I loved their fake dates and how they slowly became so comfortable with each other. Their chemistry was undeniable!
It is a feel good romance though and through.
I can genuinely say this has been my favourite read in a VERY long time. Of course I couldn't tear my eyes away from a fake dating trope unravel before me.
I was honestly besotted by the characters from the beginning and I quickly put two and two together about when they first met.
A PHD candidate and a young genius professor have found themselves enthralled in a fake dating situation because Miss Olive Smith wanted her friend to have a chance at love. Cute right? Of course it wasn't plain sailing as Olive had a lot of unresolved issues and Dr Adam Carlsen was seen as an pompous ass.
Navigating a fake relationship with nosey best friends and piercing eyes was no easy feat. Olive and Adam were thrown into some very tricky situations but I felt as though they didn't really mind so much.
Honestly I stayed up till 4am finishing this book and my cheeks hurt from grinning. My heart was melting I could see how much care and support there was and yet for people so intelligent I found myself wanting to knock their heads together! I reread page after page hanging on every word of their interactions from coffee too speeches.
Of course the fake dating was not the only part of this book but it highlighted the true trials and tribulations of academia, of the struggles being women, LGBTQ+ or BIPOC. The strength in the messaged shone through and were covered so well.
As the story developed and friendships and loyalties were tested I found myself clinging to every hope the truth would come out with the right thing being done.
I was hooked by the end of the prologue already but by the first chapter I knew I wouldn’t put it down. The fake dating and the growth felt so much more real and organic then other books I’ve read and it had just enough humour and science details to make it unique. Truly in love with this book that by 75% in I started delaying my reading so that I wouldn’t finish it too fast. I can’t wait to re-read this very soon.
