This was an entertaining story, but it had too many flaws. There was too much implied but not enough known about the h's relationship with the OM, who was married to the H's sister. You never see any flashbacks and are led to believe at the start that it was some grand passion, when in fact they never slept together, and it didn't take him long to get back on track with his wife. You don't find out if she knew he was married when she first got involved, if they were dating or just together while they were performing in the play, how long it went on, or any details.
You also don't get any details about a very traumatic experience in the h's life (the death of her parents in a boating accident, where she alone survived) until after her almost obsessive side trip to coastal Wales, which involves her hitching an early morning ride with a truck driver, getting a lift from a lady farmer on her tractor and then borrowing her horse for a time, and then hiking the rest of the way. OH, COME ON!!!! She had rented a bicycle to get her to and from the location shots, so why the heck didn't she use that??? And I'm sure there was some kind of taxi or rent-a-car service that would have made the trip a lot easier! This was all contrived to make for one of those scenes where the H shows up unexpectedly, and that really annoyed me.
It was also silly to have the h try to overcome her fear of being in a boat alone (for one of the scenes in the TV series) when you're not told why she feels that way until later on, when the story of her parents is revealed. This is a romance novel, not a mystery one, so it was silly not to say what was going on from the start. As it was, it just fell flat.
And speaking of romances, this wasn't much of one. For most of the book, the H and h are colleagues (he's the director of the TV series, she's one of the actors), and despite the chemistry between them (and a contrived stuck-in-an-elevator scene in the beginning), most of the time they're apart and dating other people. (There's a second OM in the story, and she goes out with him and makes out with him and knows she's using him but does it anyway; but he's the carefree type, so I guess it didn't faze him.) The H and h have a few make out scenes, but they don't lead to anything, and the H appeared to just want to get her into bed (suggesting a trip to Corfu with NSA).
It seems the H knew almost from the start that she was the OM his brother-in-law had been involved with, so that being the case, why would he want to have anything to do with her? He professes love and loyalty to his twin sister, and then wants to shag the woman he thinks was shagging his sister's husband???
They don't see each other for months, then meet again when he apologizes for thinking she had slept with his brother-in-law and was continuing the affair, and then once again they go for months being apart, getting on with their lives, dating other people, and then the author throws in a contrived auto accident (with the H temporarily blind) to get them back together again. Talk about DUMB!!!
Next thing you know, the h decides to dispense with her virginity and go for that extended "dirty weekend" with the H, only to have him go all prim and proper and keep separating bedrooms at the hotel! Why? Because he wants to marry her, of course!
Meantime, much (way too much) time is wasting describing the flora and fauna and geography of the Greek Isles, as well as festivals, food, etc. ad nauseum.
The only thing I liked at this point was the h's BFF/roommate showing up to be her maid of honor along with the H's good friend who will be his best man. The two have been dating and are now engaged, as well!
I liked them both better than the H and h, which is always a sign that the book's not working the way it should. And yes, another case for me where I wish the story had been about this other couple.
And here's another crazy coincidence: the h helped save the H's mother's life!! And almost from the start, the woman sees her as daughter-in-law material! Too much??? You bet it is!
BTW: the TV series is called "Penruth", it takes place in early 19thc Cornwall and is about an aristocratic man falling for a woman from the lower classes. Gee, why does that sound familiar??? Why do the names "Ross" and "Demelza" keep popping into my head???
If you skip this one, it's no great loss.
