Laney McLeod's life changes the minute she gets stuck in an elevator in Manhattan - and relies on handsome stranger Deke Sargent to help her fight her claustrophobia.
When the power comes back on, Deke and Laney find themselves in a passionate embrace that leads to a night of love. Shocked at her indiscretion, Laney disappears the next morning.
Months later, she receives an even greater shock: Deke shows up in her life with an astounding announcement. Unable to forget the chemistry between them, but afraid that she's just another notch on this wealthy playboy's bedpost, Laney is about to discover an even deeper fear...one that she must face or forever lose the one man she can't resist.
