This book was part of a trilogy of sorts, and the author did NOT save the best for last! Aside from a clever twist of making the OW/Villain of the previous book the h of this one (the only reason I'm giving this book two stars instead of one), the whole story just fell flat.
First of all, considering this h's past: blackmailing the H of the previous book into marrying her by letting her (wealthy, powerful, vengeful, morally bankrupt) grandfather/guardian think he had seduced her, and then standing by and letting Gramps threaten him and his employees with bankruptcy if he didn't make an "honest woman" of his granddaughter, it's difficult to put her in h mode. The author tried to pave the way by pointing out in the previous book that she was young (only 18), both spoiled and neglected by her crap family, and desperate to be loved, but it still doesn't cut it. Neither did her apparent redemption at the end of that book, five years older and wiser. She still comes across as spoiled and pushy, clinging to the H when her grandmother dies (the only relative who cared, though she was also flawed), despite his reconciliation with the h, and expecting him to be there for her while she copes with her loss.
That nonsense is negated in this book, when the OM makes his appearance (before the H comes on the scene) and we find out they've been friends since childhood, and she thought of him as a brother. Then why the heck didn't she turn to him when she was grieving, instead of the H????
Also, the whole silliness of her marriage (which was never consummated as the H refused to sleep with her) was never really dealt with, as you get no flashbacks and no discussions about it, like why was she divorced, when the marriage could easily have been annulled, not only because they didn't sleep together but because of the circumstances that brought it about???
And the author takes an important factor (the h's decision to redeem herself by working at the orphanage in Asia that her late grandmother built) that goes a long way toward making the h more likeable and just lets it go, with no more than a few hints at hardships, horrors, ana a bout with some kind of flu or virus that took a toll. But that's it! No flashbacks, no discussions, she never even tells the H about it! The whole thing's just completely dropped, except for her idea to build a children's camp on the island her family owned, which apparently happens, but there's not much to that, either. Ridiculous!!
What you do get (and way too much of) is one of the most unlikeable, unpleasant, and downright ANNOYING characters in HP history: the OM's wife/H's sister!!! What a WACKADOODLE!!! I won't even bother describing her (I'm guessing other reviewers have done that) but let's just say she should NOT have been allowed to reproduce (this is one case where a miscarriage should have happened) and I feel sorry for that unborn baby, hope it's kidnapped by someone sane, as this mother-to-be definitely is NOT (I don't buy that a short time of therapy straightened her out, when nothing had helped in previous years), and the OM is a weak, waffling beta wimp, (he thought of the h as a sister, but was also attracted to her, but loved his wife, but sort of loved the h too, and as for telling the truth about the h's marriage to his bat crap wife after he promised the h he'd never tell anyone, well gee, he's sorry, but maybe he resented that marriage, just like he resents the H, but not really, well, maybe a little, but Gee Whiz!), you get the idea! That poor baby will soon be yelling "HELP!!!!!"
The H is not without flaws, as he acts a bit like some of the h's in other books, where they're always too quick to think the worst of the H. Her, the H acts like that about the h, believing she's a spoiled rich princess, who plays sex games with men, and has been hitting then sheets with the OM, betraying his beloved sister, while all the time knowing what a mental wreck his sister is! And who was his source for all the crummy thoughts he had about the h? Why, his sister, of course! Who could be more reliable? (BARF!! BARF!!) Ironically, he talks about how coddled the h has been all her life, while he continually coddles his lunatic sister and makes all sorts of excuses for her! He even tries to put the blame for her failing marriage on the OM, who (though no prize) didn't deserve that blame, considering what he had to put up with.
And it got tiring to hear the H talk about the h's lack of morals, character, whatever, while making it clear how much he wanted her, couldn't stay away.... until he did! Right after he seduced her! (Later, he says he realized she was a virgin, but it didn't register because he thought her marriage had been a real one, that the OM had been her lover, that there were others as well, etc. and SO SILLY!!!
So many things didn't fit. At one point, the h said there had never been any men in her life until the H except her ex and the OM, but then she mentions men trying to get their tongue in her mouth when they kissed her, so how does that make sense? She never kissed her ex, and kisses with the OM were the brotherly peck on the cheek, so there had to be others, didn't there???
The H and h go the one step forward/ten steps back too many tomes, and it gets annoying. And there was no necessity for that silly episode toward the end when the h thinks the H is dead, killed in a boating accident. It served no purpose at all, and was so short (one day he's "dead", the very next day you find out they identified the wrong body) it may as well not have been written.
Then again, that's true of the whole book!
