I received a copy of this book from the author in exchange for an unbiased and honest review

Gabby is a brilliant M.I.T. student spending the summer in her grandmother's house, the last summer it turns out as her parents have decided to sell it after the grandmother's death. Gabby was close to her grandmother as she accepted Gabby for who she was and wasn't forever disappointed in her choices the way her parents always seem to be, so she is greatly saddened by this decision. As Gabby wal
This book has lots of elements I like. A smart heroine who is nerdy. Love it. However, the opening didn't sit well with me. I just didn't like the tone. I didn't care for the voice of the heroine.

I admire the fact that the writer is working with the idea of empowering her heroine to get her sexual needs met. However, this pursuit felt strained to me-- unorganic to the character. Perhaps it was opening with those needs instead of the needs being intergrated into the development of the character

Where to start? I liked this book. It was short and cute and since I’ve been reading all violence and MC books this month, it was quite a buffer.

The Duality Principle is set in Portland, Maine, where Gabriella Evans is on vacation, staying at her deceased grandmother’s house. She’s a brilliant mathematician from M.I.T. and a complete rebel. She’s tired of having to live up a prim and proper life thanks to her parents’ expectations of her. So now that she’s away from them for the time being, she

This book was hot, sweet, and fast paced. I read it all in one go. I loved the premise behind the book. Smart is totally the new sexy. Gabby was hot and so was Connor. They both are brilliant and it was interesting watching the two of them get to know each other while trying to figure out how to get what they wanted.

I really found it interesting how they were both struggling to verbalize what they were looking for in prospective partners. The back and forth between Gabby and Connor fighting the

Be yourself.

It's something that people say over and over again, and yet only a few dares to follow.

Gabby and Connor are two characters who can't help but hide their real selves for different reasons. All around Gabby, people have certain expectations of her that when she doesn't conform to it, she gets hurt by their actions or words. On the other hand, Connor had a wild streak before that earned him such a bad rep with everyone in town. This story is them finding the balance

My Review:
This is a fun little story. Gabriella is a nerd and the guys she meets are complete duds. They don't understand her or her need to get a bit dirty when it comes to sex. They just don't expect or want that from this MIT student. She has a nerd exterior but the heart and libido of a bad girl.

Connor has the opposite problem. He's trying to shed his bad boy persona that's only brought him trouble. Now he's a computer programmer and is trying to make that who he is all the time so he can m

What a fun story! A true Tell Me A Story kind of story.

Love when I am completely entertained from start to finish, no over the top drama or antics, just a good read.

Fantastic debut and am looking forward to more from this author!!

It is really great to see how mathematical theory gave an idea for a romance novel. I found that very fresh and original, but even more amazing is how the author incorporated the duality principle theory in the story.

Because of this, but not only this, “The Duality Principle” is a very enjoyable story...

Really enjoyed this one, y'all.

Full review to come. :)
I have somehow forgotten how I stumbled across this book, but I bet there is a good story behind it. The Duality Principle by Rebecca Grace Allen is a contemporary romance that is based on quite the “brainy” principle of duality. The heroine Gabriella Evans is doing her PhD in disproving the duality principle which states that “if a theorem is true, it remains true if each object and operation is replaced by its dual.” Gabriella is not just super intelligent, she is also someone who is tired of ...more

I've been a huge fan of Rebecca Grace Allen's for years, and when she asked me if I'd like an eARC of her debut, the words HECK, YEAH left my mouth so fast they left skid marks. I did not promise a good review in exchange for the book, only an honest one. Fortunately, I can give both.

The Duality Principle is set in Portland, Maine--a city I never had any desire to visit until I read this book. Ms. Allen paints a lovely picture of this seaside town and does so without going overboard. Just enou

With The Duality Principle her debut novel, Rebecca Grace Allen nailed it.

This story is about a geek who desperately wants to be a little naughty and bad, and about a bad boy who desperately wants to be a good, tame geek.

Gabriella (Gabby) and Connor definitely area match made in heaven, only it takes them a little time to realize it. During that time she sure have a blast, though. Damn, I forgot how dirty RGA’s writing is sometimes.

While Gabby is pretty much the same – a brilliant student, sexy

A sweet ride. I enjoyed this book. It was so simple and yet so full of terms and some sexy geeks. It was good combination.

Connor was sexy, hot and stubborn. He was just in his own head so much, thinking for Gabby and changing himself, which was no good. But I still loved how sweet he was, and how he was willing to try for her.

“So be different.”~

One of my favourite things this year in books is that Smart and Geeky is the new "Sexy" and The Duality Principle by Rebecca Grace Allen is another book to back that up. In this book we meet Gabby Evans who is studying her PhD in Applied Mathematics with the theory of The Duality Principle, which states that no one single entity can represent two things e.g you can only be good not bad etc. After her grandmother died and things became rocky at home, Gabby needed time away and heads to her Grand ...more

My Thoughts:

I just knew that upon picking up this story, I would be caught up in a whirlwind romance. It wasn't unfounded either--I definitely got drawn into their story immediately, and found it very hard to tear myself away from it once I started.

Gabriella and Connor are hard to resist--and an absolutely perfect blend of naughty and nice. There's a mix of wanting to be good and wanting to be bad that has these two with a little b

I was given this book for free in exchange for an honest review.

I enjoyed this book. The characters were so perfect for each other and the ending was believable and not too cheesy--important requirements for me when considering whether I like a romance.

Connor is the town bad boy and Gabby is an uber smart woman on her way to earning a doctorate. But neither is what they seem on the surface. When they get together, they have to work at stripping away one another's masks, and they end up caring e
As a former graduate student, I’m particularly sympathetic to books with leading men/ladies in grad school. So when my dear friend Cosmo read/reviewed The Duality Principle (TDP), Rebecca Grace Allen’s debut novel(la), featuring a spunky, sexy Ph.D. candidate, I knew I’d have to give it a read. As luck would have it, I won a copy of TDP in a contest that Rebecca hosted on her website. I’m certainly not one to eschew fate, so I dove into reading right away. As I suspected, I adored The Duality Pr ...more

I loved "The Duality Principle" because it sucked me in from the first pages. Who hasn't been told that you can't be yourself because if you are then you're not good enough or no one will like you? The story of nerdy girl Gabby and ex bad boy turned IT geek Connor go through this exact thing. Both are too afraid to be themselves with the other because they believe that their true natures will scare the other off. Will they work through it and reveal themselves or end up losing in the end?

Oh I loved this book. I was just in the mood for it. Gabriele is a budding mathematician studying at MIT. After her grandmother dies she goes to spend a summer in the house that always reminds her of carefree summer holidays and gives her the peace to write her thesis on duality: a running theme throughout the book.

Tired of her projected good girl path, Gabriele yearns for the passionate, spontaneous kind of love that has never come her way. She knows her sexual adventurousness is at odds with

The setup: Summer, Portland, Maine, a seaside town. Gabriella is a math major who hides some of her naughtier desires (namely, outdoor sex and spanking) under her geeky exterior. Connor is a cute motorcycle rider who's determined to be straitlaced after the rebelliousness of his younger days. When Gabriella and Connor are set up on a blind date, she likes him and is intrigued by the glimpses of something edgier.

They meet on a blind date and Gabby's first thought is that he is just another nerdy guy but she finds that Connor has layers and a wild past that she would like to experience a bit more.

It was fine. I think I'd have liked it more if I wasn't bored with the whole angsty "BUT WHO AM I?" thing young adults go through. I'm much more interested in stories that explore people who know who they are but struggle to figure out how to interact with the rest of the world.

The Duality Principle is a fun, quick, and engaging read with some the sweetest and sizzling moments that will touch your heart. I really love a heroine that's not just sexy but also smart. She's a woman that knows what she wants and isn't afraid to go after it. And add a hero that's a bad boy who wants to be a better man for the girl of his dreams and you've got yourself a passionate love story.

There are some intriguing and provocative scenes that will get your blood pumping and the drama will

Gabriella is spending the summer in Portland away from her maths PhD. While she's fantasizing about bad boys on bikes, she's being set up on blind dates with sweet nerdy boys who wear their cell phones attached to their belt loops. Connor is just that nerd. He's working hard to be the good boy, especially because he thinks that's who Gabby wants, but to do that he's hiding both his past and his desire to get down and dirty with Gabby in any number of public places.

There was a lot I loved about The Duality Principle, it was light and fresh, while still managing to be thought provoking and hot. This combination was fun to read. I have to admit I didn’t necessarily know where the story was going in the beginning and I was unsure what to make of the two main characters, but regardless, I couldn’t seem to put the book down, and once I found out more, I needed read it all.
