I’ve been looking forward to reading Quan’s story for a long time, and while I really enjoyed reading it, there was just something missing that kept it from being a winner. The Heart Principle was more of an emotional read than the previous two, but it still contained the light-hearted, romantic charm of the rest of the series.

I don’t believe I’m in the minority when I say the best part of The Heart Principle is: Quan. After surviving cancer, he has his own insecurities and anxieties to overcome. I really loved delving deeper into his character. I was already a big fan of him, but this book made me love him even more! The chemistry between him and Anna was also really well written! The way in which their relationship develops was beautiful and felt organic.

There was a lot of focus on Anna’s family and her personal growth, which I didn’t mind, but the tone of the book felt very different from The Kiss Quotient and The Bride Test. The book is also written in first person POV instead of third like the previous two books. Neither of which were bad changes, the book just didn’t give me the same giddy, heart-fluttering feeling that I had when I read The Kiss Quotient.

Overall, The Heart Principle is a romantic, heartfelt story full of excellent character development and examines heavier topics such as family loss, caregiver burnout, and cancer. Quan and Anna’s chemistry deserve all the praise, and I really enjoyed the way their relationship unfolded.
