Bigger Rock

Yes, all the girls want the big rock. And who can blame them? A big rock means the guy went all out on the proposal and the ring.
Not this time. Spencer Holiday is the son of a jewelry store magnate. His Father had run Katherine's, an upscale jewelry store named for Spencer's mother, for years. Now that he's looking to retire and sell, he needs Spencer to play the polished businessman he can be rather than the unrepentant playboy role Spencer prefers to embody. Katherine's is a very family friendly business, and the buyer is very into a wholesome reputation.
When a misunderstanding about his best friend and business patter Charlotte arises, Spencer comes up with a brilliant plan to rehab his reputation with the unimpressed buyer: a fake fiancee. And who better to pick than his best friend, the person who knows him better than anyone else? And, after all, they've had a standing agreement to play each other's significant other when necessary over the years. Charlotte agrees, with a request of her own: that Spencer end the long dry spell she's had. They set the terms, the official story, and the timeline. And Charlotte gets a big rock, because the son of the founder of Katherine's wouldn't do any less when he got engaged than pick up a big fat rock.
But what can be do when they start to break the rules and he realizes that his fake engagement is the one thing he wants to be real?
Told in Spencer's POV, Big Rock is masterfully written. There's sweet and sexy and downright steamy all in turn. A great read. And the proof positive that sometimes a best friend is forever, though not always in the way you might anticipate.
