Having read and mostly enjoyed the previous books in Anne Gracie's Merridew Sisters series, I really wanted to like this one. Unfortunately, I found too many aspects problematic and disappointing.
First of all, "The Perfect Kiss" can't seem to make up its mind whether it wants to be a Gothic, a fairy tale, a Manipulative Will story, or a road romance with touches of the exotic. It combines elements of all of the above--a rich, beautiful heroine disguised as a dowdy companion, ancient prophecies trembling on the brink of fulfillment, unreasonable legal conditions forcing two painfully incompatible people together, and a night spent in a harem--but not that successfully. The book might have gotten away with tackling two subgenres, but four?
The characterizations present another difficulty, especially within the context of the plot. In a nutshell: glamorous Grace Merridew masquerades as the aforesaid dowdy companion to help her timid best friend, Melly Pettifer, resist an arranged marriage to a mysterious, much-traveled lord only to fall in love with the prospective groom herself. While not very original, the bare bones of the plot seem serviceable enough -- except that at least one key relationship never rang true for me. Although I was told repeatedly that Grace and Melly were best friends, I felt that I was never shown WHY they were close or what drew them together, despite their different personalities. It was never clear to me why Grace would go to such trouble to help the spineless Melly, and their so-called connection is further weakened by the ease with which Grace repeatedly dallies with Melly's betrothed.
Dominic, the betrothed, does not exactly cover himself with glory either -- ready to abandon his estates and dependents out of a childish desire for revenge against his late father and treating his unwanted fiancee with an indifference bordering on contempt while he energetically pursues her "companion." And while Melly herself is a weepy, spiritless wet noodle, she may still deserve better than to be treated so thoughtlessly by Grace and so callously by Dominic. I found it hard to sympathize with any of them.
In other circumstances, I might have enjoyed Grace and Dominic's romance. Grace's intrepid spirit was one of her more appealing traits in the earlier books and Dominic partially redeems himself when he awakens to his responsibilities as lord of the manor. However, the clunky plot contrivances designed to keep them apart and the couple's rather shabby treatment of the pathetic Melly, who's decidedly not in their weight class, add up to a less than satisfactory read.
