Five years ago, Kat Harper fell into a dizzying summer romance with her brother's best friend, Bryan. It was a mad, crazy love full of kisses all through the night, but he broke her heart and she had to move on. Five years later, Kat is finishing her graduate degree and building her business as a jewelry designer, when Bryan, head of his own successful company, walks back into her life. Bryan has been assigned to Kat as her new business mentor and the rules are clear. No hanky-panky permitted. Kat can handle that because she's totally over him . . . right? Except, he still makes her laugh, and he remembers all the things she likes. Not to mention that he's even more handsome now than he was then. Then there's the spark between them-the simply undeniable chemistry and the tender ways he shows he still cares for her. Can they resist each other the second time around or will first love trump all?
