Sadly this was a really poorly written book. It seemed like the author had done limited research in the characters supposed backgrounds. You have a russian billionaire who is a whimp, an accountant who is extremely illogical and more than a little crazy, juvenile dialogue and actions.
The heroine and hero fall in love but I never saw it, I never felt any heat from their encounters. We weren't helped by the poorly written book. My personal favourite from a sex scene is the sentence which starts "They duck walked down the hall to the door at the end of it" WTF kind of a description is that? In a sex scene? We are also told frequently about the colour of the hero's eyes - blue, ice blue and variations thereof.
The book could have been good it there was actual research, well written dialogue and prose. Oh and actually showing two characters falling in love. This book demonstrated none of these. I wouldn't recommend it, at all.
