The Heir by Georgia Le Carre

Rosa:
With those searing whiskey eyes, chiseled face, and cocky attitude it was pretty obvious he was a player. Ordinarily, I would have been able to resist him, but it was my best friend’s wedding, and I’d had a lot of alcohol, so I thought, what the hell. At the very least he’d have the skills, and judging by that huge swell in his pants, the equipment to give a bridesmaid a good time.
Of course, we used a condom, actually, a few, but one month later I’m sitting on my bathroom floor looking at five pregnancy sticks all lined up. Each one telling me the same thing: Girl, you’re pregnant.
Clearly, he won’t want to know, being a player and everything, but my best friend says telling him is the right thing to do.

Looks like I’ll have to go to Italy to give him the bad news.

Dante:
I wasn’t asleep when she woke up that morning and crept out of my hotel room. For the first time in my life I didn’t want a hook-up to leave, but that made me more determined than ever not to see her again. I liked my carefree life too much.
I left England and flew to Monte Carlo. The big plan was to hit the casinos and lose myself in other women, but I got back to Italy and simply couldn’t forget her.
A month later out of the blue, she swans back into my life to drop her bombshell.
I let her slip away once. I won’t again. This time I’m doing the unthinkable. I’m going to limit myself to just one woman.
I’ll show her I can be the perfect daddy.
This woman and the baby in her belly are going nowhere.
