This book is a reprint of the original, circa 1979. If you were a fan of Harlequins in the late 70's - early 80's, go for it. However, if the thought of a chain-smoking, misogynist hero who's 20yrs older than the dippy virgin heroine makes you cringe, stay far far away. As a child of the 90's, the un-PC language was enough of a turn-off for me (his butler/personal assistant is described as a "small, slender Oriental") but the entire book wouldn't have been much improved by a language face-lift.
The 'unavoidable accident' mentioned in the description? She's speeding and spaced out in a motor boat and clocks him on the head when he's swimming. I'd hardly call that 'unavoidable', but it almost works to balance out his appalling behavior for the rest of the book. All in all, I'm hard-pressed to think of another romance novel character I've disliked more than either of the two protagonists.
Zero stars should be a possibility, but I might have given this book one star in any case because it's actually kind of amusing -- in the way that some truly terrible made for TV movies are so bad they're funny.
