This was a simple sweet romance; light and easy to read. The characters were likeable enough, but you don't get a lot of depth. There is no real intensity of emotion! There were a couple of issues/inconsistencies, that didn't make sense...such as:
Why are two adults still living with Mom and/or Dad? I can understand the, h to an extent. She's a single Mom who helps support her parents; they help with her son; and they are all just barely surviving. But the H lives with his retired Dad (or his Dad lives with him, we're never told who owns the house); his Mom died when he was young. Considering the H was previously married and divorced, and a billionaire (?) to boot, why would he be living with Daddy? We're never given any reason.
And that's another thing, he's supposed to be a billionaire (according to the title), but nothing in this story supports that fact. Instead, it suggests the opposite. At first, you're given the initial impression that he OWNs the consulting firm (he's CEO). You think okay...he owns and runs a huge successful consulting firm in NY. But then you get a few little things that lead you to believe the consulting firm is not that big of success yet. Rather it is on the brink of being a major player/success. Later we discover it's not even HIS company, just one he runs. (He quits at the end...you don't quit a company you own, you sell it maybe, but not quit.) And okay, so he's CEO and CEO's of major corporations can earn in the millions...but Billions? Not likely, and he's not old enough to have earned billions investing. And if he was a billionaire (or even a multi-millionaire), why was he so cautious when starting his own business? Why the need to start small, then expand slowly, cautiously because he didn't want to "risk all his savings"? Really? Would a billionaire (or even multi-millionare ) worry about his savings? At best he's well off...drives a Lexus and a motorcycle, has a nice house; but nothing in this story intimates he's billionaire status, other than the title, and honestly....not even millionaire status is applicable. It's almost as if the author wasn't sure who her characters were or she forgot. She'd have done better leaving the Billionaire out of the title.
Another thing, the h is a virgin when she first encounters the H. You assume, as she was still a virgin and had never had time for relationships, that she wasn't on birth control pills when she hooked up with the H the first time. Why else did she end up pregnant? But then some time after they'd reconnected (4 yrs later) when she finally tells him the kid is his, we get a "but you said you were on the pill? ", and she replies something about the pill not always working. Mind you, whether or not she was on the pill, was never asked, discussed or even mentioned at their first encounter. And come on....99% effective and first time??? It would have been more believable if she hadn't been on the pill and he'd just assumed she was and she didn't think about protection due to her lack of experience and excitement.
In spite of those things, and if you go into this with the perception the H is just a very comfortably, well off guy, then as I said, it's simply a sweet love story. Think of this one as a "palette cleanser" or mind/heart cleanser. You know, something you might read after you've just finished one of those stories that was so intense, so emotional you felt like you were on a roller coaster, but you didn't want it to end and now you have a book hangover and just aren't ready for another book because you're not ready to leave the characters yet. This story will clear your mind and heart without leaving any residue so you'll be ready to move on for the next emotional roller coaster read.
