This is the story of Adelina, one of the Santoro sisters, and Matteo, leader of the local MC.
I have to say that sooner Matteo made me fall for him. All that bickering with Adelina to get her to open up to him...
But he soon proved himself underserving of Adelina because yes, she is a snob and a spoiled child who doesn't know what she wants though he, as a grown man should know how to keep his word (and incidentally the penis in his pants) Dude? On your wedding night?
Not only that, but after his wife's assault he decides not to sack the vicious man who committed the crime under the excuse of being short of men.
And later, instead of assuming responsibility and telling the truth about everything that happened to his brother-in-law, he decides to keep quiet for the business's good.
A gem of a guy.
The book reads in one sitting and has a HEA.
