Leah McAllister is starting a new job in a bland maze of tan cubicles where she hopes to blend in with her surroundings - she's had enough attention for one lifetime. What she never expects is to find herself working under Morgan, a mesmerizing woman who turned her world upside down when they met one year before. A lot can change in a year, though, and Morgan Park is a different person now. She's reserved and sullen, and trying to get over a broken heart that came with a heavy dose of guilt after her troubled girlfriend, Allison, disappeared one day leaving Morgan with nothing more than a vague goodbye note. Thrust together in the cramped quarters of a cubicle, Morgan and Leah can't deny - or resist - the forces of attraction driving them together. Morgan even begins to think she can find happiness again when Allison suddenly blows back into town with a terrible secret that threatens to tear Morgan and Leah apart permanently. Is the mystery of Allison's lost year enough to destroy Morgan and Leah's budding relationship?
