After getting hurt in college by a gorgeous guy, Nicole Magette invented a system to protect herself from future heartbreak. Now she lives a satisfying life. Her work is easy, her friends are her family, and the only men she cares about are her cats. She only hooks up with losers who won't threaten her heart, but she has a failsafe just in case they do. In college, Nicole invented the "Code Red." Though her friends have given up on the concept, Nicole has used it to keep away men who could worm their way past her carefully constructed walls. It's kept her safe for seven years. Joshua Daniels is Nicole's new coworker, and she's been assigned to work with him on a special project. He's everything she's avoided, everything she claims she doesn't want. Can the Code Red save her this time, or will Josh send her perfectly balanced life into chaos?
