Hazel Brentwood and Callum O'Daire are from two different worlds, but they both need each other. Hazel is well kept in high society. Callum is a self proclaimed "street rat" who has risen above and has become a powerful entity in Boston's high and low societies.
Hazel is adopted. After finding some leads left behind by her deceased brother (who Callum may or may not have history with), she is in need of Callum's help to identify her birth parents. Callum is also in need of information in regards to the death of his father and childhood friend. (Both of who died at the same docks that Hazel's adoptive father owned.)
Callum agrees to work with Hazel, as long as she sleeps with him. Hazel is hesitant, but their instant and unexplained attraction for each other, and her desire to find answers, keeps the story going and readers on a steamy and interesting ride.

My takeaways and thoughts:
The couple is the epitome of light vs. dark. The banter between Hazel and Callum was steamy and fun to read. Their hate/"love" relationship that they have was what kept me hooked.
This is labeled as a mafia, enemies-to-lover romance, but I do not believe that much of the mafia world was added to the story. However, it is very much an enemies-to-lover story which I am here for.
I believe that this world the other set up had a lot of potential, but it wasn't explored as thoroughly and that's what made me give 3 stars.

I have literally just finished reading this novel. Oh my goodness, it is so exhilarating and passionate. Just reading it gave me a rush. The thrill, the adrenaline and just the story in general ticks all the boxes for me. I thoroughly enjoyed the read. It more the exceeded my expectations. It was that good that I almost didn't get to go and do my shopping because I was so entranced and glued to this book out of sheer fascination and intrigue. I would highly recommend this book. Well done on a great book.
