One in a Million by Kimberla Lawson Roby

Kennedi Mason thinks she's the luckiest woman on earth. She loves her job, she has a wonderful best friend, and she's been married for ten years to her soul mate. There's nothing she can think of that could make her life any better.

Then one fateful day Kennedi receives a piece of news that will turn her world upside down. She's excited about it, and she knows that her husband, Blake, will be over the moon. He has always dreamed of this one thing happening, and she can't wait until he comes home so she can tell him.

But when she sees Blake that evening, he has a special announcement of his own. It shocks Kennedi into silence and wipes the admission she was planning to make right out of her mind. In an instant, her life and her marriage have changed, but not at all in the way that she had expected.
