I picked up this book to see just how the author would "weave in the exciting profession of competitive intelligence," as mentioned in the acknowledgments. It turns out, the author does a minimal job of describing the profession or using it to motivate the character Zach's behavior.
This book has all the basic ingredients - reunited lovers, a mysterious disappearance, an autocratic, disapproving father, etc. - but the whole thing falls flat and drags on far too long. Because of heroine Victoria's sister's disappearance, Victoria and her formerly spurned lover Zach are driven to discover the connection between an elite secret medical facility and a world wide drug syndicate. The few details they do manage to uncover become more and more ludicrous as the story unfolds. You also have to pretend the bad guys are so arrogant and busy with their evil money making schemes, they won't recognize the lovers when they infiltrate the clinic, even though they've been following Victoria from the beginning.
The characters are unidimensional and pretty unappealing, good and bad guys alike, so there's not much emotional impact when a chief suspect turns out worthy of redemption, and a seemingly innocuous sub-character zooms into focus at the end.
The author does have a nice touch with the sex scenes. Other than that, there are many more engaging reads out there in this genre.
