The No Strings Theory (College Boys of New Haven Book 4) Kindle Edition
Dallas
Kai’s nothing like I expected.
The scrawny kid I once knew is gone, replaced by a nerdy, curious young man who crawls deep under my skin. The moment he enters my life, he disrupts everything.
I don’t do attachments. I don’t do dates.
There are so many other college guys to keep me distracted.
Yet I can’t get him out of my head.
I shouldn’t want my best friend’s little brother. But I’ve never been great at resisting temptation.
What starts as messing around in secret, soon becomes a lot more serious. I’m gambling my friendship and risking more than I should. But I’m falling, and I’m falling hard.
Kai
I’ve had a crush on Dallas since I was old enough to crush. He’s my oldest fantasy; my only fantasy. He’s also an obnoxious, insufferable, smug jock with the stupidest adorable dimples and a gorgeous… Uh… Where was I?
Oh right, he never noticed me except when I was the punchline of his jokes.
He’s also the very definition of a guy I shouldn’t want. Just ask my big brother; he warned me time and time again not to look up to Dallas. He’d lose his mind if he only knew the things Dallas and I did when the lights were out.
But Dallas and I have an agreement: no strings attached. That way, we get to have fun and nobody needs to know. I get to live out my fantasies, to get them out of my system. No harm done, right?
Yeah. I was dumb enough to think my crush on him wouldn’t come back to life. It’s not gravity that’s pulling me in.
Now I’m falling for him faster and harder than ever despite knowing what’s at stake.
The only way this ends is with a lost friendship and a broken heart.
It’s too late anyway. I’m in free fall already.
The No Strings Theory is the fourth book in College Boys of New Haven series but it can be read on its own. It is a full-length story featuring best friend’s younger brother, forbidden love, nerd/jock relationship, close proximity, and the happiest of endings. Sink your teeth into this sweet and steamy romance.

- Reviewed in the United States on May 26, 2022When your best friends little brother is all grown up it's all bets off. I love seeing a playboy fall in love. It's so hard for them to admit their true feelings. It's cute seeing them figure out that they really do want someone to love, they're just scared. This one's doubly good because it's his best friend's little brother that he falls for. I loved the book but I wish the HEA was a little more promising especially because it's 3.5 years later.
- Reviewed in the United States on September 17, 2023I love the idea of Dallas and Kai have a history that makes it seem unlikely that anything could happen between them. These two are just so much fun as they both seem to be headed to the same conclusion and they just have to realize what the other one is thinking. Another great addition to the College Boys series.
- Reviewed in the United States on October 15, 2021I just can't get enough of this series and Hayden has knocked it out of the park again with this one. Just when I didn't think I could find another couple I loved better than Liam and Miles, Dallas and Kai walk into my life and I don't want to let them go. This book was so irresistibly charming, heart warming, playful, incredibly sexy, and so much, much more.
Dallas and Kai are the epitome of the forbidden love trope with Dallas being Jordan's BFF and Kai being Jordan's younger brother. While Kai has crushed on Dallas since he was young, it took some time for Dallas to take notice, but once he did, that soft flutter in my belly didn't stop until well after I finished the book.
Page after page, you could just feel these two falling in love, and while they were risking a lot, sometimes it's worth it to jump in with both feet first. Sometimes the thing you didn't know you wanted and needed, may have been right in front of you all along.
This book gets 10 stars, because 5 isn't even close to being enough to what this deserves.
- Reviewed in the United States on December 13, 2023This book had me laughing, crying, resentful, hopeful and wishing I had this kind of relationship. It doesn’t make a man less of a man to love another man. It’s one human loving another.
- Reviewed in the United States on October 18, 2023Pretty good romance story, but I only read about 70% and gave up. Dallas's casual attitude about sex, disinterest in any kind of relationship, disinterest in any kind of tangible future, basically made me disinterested in seeing them continue.
- Reviewed in the United States on October 13, 2023Although another novel in the series, it could stand on its own. The characters are endearing and well rounded. It was Interesting watching the angst and fear develop. Of course the end is blissful.
- Reviewed in the United States on October 16, 2021Dallas and Kai are my new favourite couple in the College Boys of New Haven series. I adored their relationship! Their bickering is downright cute, always putting a smile on my face. Kai is sweet, inexperienced and eager, crushing on his protective older brother’s best friend for as long as he can remember. And since Dallas is known for his hookup ways, neither guy lets himself believe that they want more than a no strings relationship. But Dallas is more than the smug, confident jock he appears to be, and I enjoyed watching him slowly come to realise that he is, in fact, worthy of love. The times he was vulnerable and opened up to Kai were surprisingly emotional and heartfelt in this otherwise fun and sweet nerd/jock romance.
- Reviewed in the United States on November 10, 2021A nerd and a jock!! Secret crush and protective brother!! The ingredients were all there, and they mixed well for this story of love blossoming in college…
I enjoyed the slow burn of Kai and Dallas as they started their journey, first as roommates and finally as the lovers they were destined to be. This series has me smiling, laughing, and almost jealous of the happiness they succeed in achieving.

5.0 out of 5 stars A fabulous read
This book takes us back to New Haven, the 4th visit and my favourite one so far. Best friend’s brother, close proximity, nerd and jock - this has something for everyone. Dallas and Kai are both absolute sweethearts and you cannot help but become invested in the building of their friendship and relationship as what starts as a one time thing becomes so much more. And the epilogue? Well it was not what I expected but I loved it.
In my humble opinion, It is impossible for Hayden to write anything less than amazing; and this book feels like a big hug; it draws you in, makes you smile, makes you feel warm inside and is something you never want to end ❤️

5.0 out of 5 stars More Than A Crush.
MM, Best friends brother, Nerd/Jock, Close Proximity, Romance. An easy to read page-turner with great characters that reads as a stand-alone with no loss of enjoyment or understanding. A fun, sweet and steamy college based romance with some light angst, an enjoyable read. Guaranteed HEA.

5.0 out of 5 stars Excellent
Excellent tale of two guys finding out they secretly loved each other for years without doing anything about it because of a promise made to a best friend who is the brother of the second guy. Thankfully fate drew them together at college leading Kai and Dallas to explore their feelings for each other and finding love
