The Uptight Billionaire by Cristina Ryan

He’s serious and composed. She’s spontaneous and carefree. Pretending to be in love is no big deal, right?

Alec’s doing good for himself running a successful business, until his ex-fiance returns to his life as his company’s top client. Even though she left him at the altar years ago, she wants him back. Enter Callie, a complete stranger, who takes it upon herself to save the day. She’s outgoing and spirited and pretends to be his girlfriend. He goes along with it. After all, it’s his best option. Alec has no desire to get serious about someone again. Besides, Callie is too easy-going and audacious, not his type at all. Faking a relationship shouldn’t be hard to do, except the more time he spends with Callie, the harder it becomes to resist her charm.

Callie is in between jobs and struggling to take care of her ailing dad. So when she spots an obnoxious woman unhinging some gorgeous guy, she decides to have some fun. Pretending to be Alec’s girlfriend at a business dinner proves to be just the thing to distract her from her daily stress. Besides, there’s no way she could really fall for him. She can’t put her heart on the line again. Not after what Steph did to her. But Alec’s mesmerizing eyes keep distracting her. Can her heart heal enough to allow him in?
