Captured young and enslaved by the Romans, Sabbio died while building Diocletian's palace. For seventeen hundred years he has haunted the city of Split, watching and listening as people pass through the old palace; but he is always alone. One afternoon he spies a handsome but sad man at a café, and Sabbio is intrigued.

Eight months earlier, landscaper Mason Gould's husband was randomly murdered. In an attempt to comfort him, friends and family take him on a trip to Croatia. A local woman offers to help him contact his husband's spirit, but they connect to Sabbio instead.

Mason and Sabbio quickly make an emotional connection. But Sabbio is a ghost and Mason must return to California. For two men centuries apart, it's going to take a miracle to make love work.
