She wasn't his mistress, it was only a one-night stand which resulted in pregnancy, and the scandal which wasn't a scandal seemed to be forced in the text.

Ellie (Eleanor) Jensen is Brazilian billionaire, steel/iron magnate, Diogo Serrador's youngest executive secretary. A country girl, with little education due to circumstances of her childhood, she is an epitome of innocence and naivete who gets swept into Diego's arms in a lustful one-night stand, and falls in love with him. The book starts straight away with a shocked Ellie reaching Diogo's Manhattan offices to inform him of her pregnancy, and to hand in her resignation. Within six hours she is going to get married; married to the same person from her hometown, Timothy Wright, a lawyer who had since resigned from Diogo's payroll (and who Diogo detested?), who had helped get her the job in the first place.

Within a few pages, the scene is mind blowing, Diogo thundering through Ellie's wedding, and whisking her away! And what follows later is two totally unexpected surprises!

I never saw the bombs coming...
And then what a sweet family reunion there is! Just when I thought the story was maybe over, in came the real, the biggest, baddest villain. I was waiting for his comeuppance. And then, a typical Bollywood masala movie ending.

Action-packed book, highly recommended! After reading digitally, I am even getting a paperback as this one's for keeps, and for re-read.
