Strings Attached

For Gracelyn, life had always been that of splendor and frills. She had been raised to be spoiled. Raised with anything and everything she ever wanted. But her twin, Katelyn, she had been raised with a less frilly life. Raised in a lower class area and with her less fortunate mother, Katelyn had known no riches and no splendor.
One is snobby and one is stubborn. One is heavenly and one is a bit of a hellion. One is selfish and the other the kindest and gentlest soul. One is just what Shaw thought he would get out of the deal and the other is exactly what he needed in life.
At twenty-two both girls, though not knowing the other existed and the differences in each other's lives, had both been kept under strict proverbial lock and key. Every move they made had been watched and calculated. Why? Gracelyn didn't really care and Katelyn didn't really know about, that is until a family gather has been called and an uncle had announced an engagement to a man who she had only know from his reputation.
Shaw McDaniel hadn't expected to accept the strange proposal offer when Roger Newberry had brought it to him but he had to think about it! The offer that had been presented by the Holbrook Corporation, specifically from Colton Holbrook, the CEO and founder, was just astonishing. But even Colton Holbrook knew of Shaw's little flings...
But could Katelyn be hiding a secret? Or is Gracelyn? Do they share the same strange tendencies... Ones that most don't know about them and that is the fear of someone getting too close. Who is afraid to let someone in and afraid to get close to anyone?
And then there is Shaw who is more than meets the eye as well. His whole world goes deeper than many know.
How does one mistake mix up the girls and cause the proposed agreement to go all haywire? Maybe just have to read and find out...
