When it comes to the confident, charismatic Caleb Parker, Sadie Lane feels the spark--the kind that comes from rubbing each other the wrong way. She's yoga pants, he's a suit. She's a tattoo artist, he's a straight-laced mogul. But after they accidentally co-rescue an abandoned dog from a storm, Sadie sees a vulnerable side to the seemingly invincible hottie. Caleb doesn't do emotions. Growing up the underdog, he's learned the hard way to build up an impenetrable wall. Perfect for business. Disastrous for relationships. He's never worried about it before--not until he finally gets behind Sadie's armor and begins to fall. Both guarded and vulnerable, Sadie and Caleb are complete opposites. Or are they? Shocked at their undeniable connection, can they ever admit to wanting more? That all depends on what they're each willing to risk.
