When Jack and Siobhan divorced, the truth is, neither really wanted it. But anger, misunderstandings and the inability to communicate with each other, despite more than ten years of marriage, spun things out of control and the divorce happened anyway.

Neither, however, has moved on, though four years have passed.

Now fate and circumstance have conspired to re-unite them as they help arrange the last-minute Christmas wedding of friends. The facade of icy indifference with which they have been dealing with each other while sharing custody of their children begins to crack. When the two of them end up accidentally locked in a wine cellar, it finally breaks wide open, melting the ice and turning it into steam heat.

With wedding fever and Christmas magic in the air–and a little help from a couple of four-legged elves–Jack and Siobhan may just find out that sexual chemistry may not be all that is still between them.
