It Was Always You by Scarlet Ellis

How far would you go to help your hunky best friend?

Gorgeous and wealthy playboy Leo Cormack has worked hard his whole life for his birthright – control of the family business. But just as the company is about to be handed to him, there is one little problem, and her name is Kylie Musgrave. America’s sweetheart supermodel and Leo’s bitter ex-lover is out to ruin Leo’s reputation by telling the world scandalous lies. Lies that could destroy his chances of inheriting the company.

The decision to give Leo the company is put on hold until the mess can be dealt with, and so Leo needs a plan, and he needs it quick!
Enter Jessica, his beautiful and sexy best friend since college and the perfect decoy. It would be simple, they would fake a marriage to take the heat off of Leo and the family business, and once the plan had worked, everything would go back to normal.

But it soon becomes clear that things will never be normal again. The lines between real and fake start to blur, and Jessica and Leo are forced to confront their real feelings for each other.
