Twenty years ago, a father writes a letter to his last surviving ancestor. Written on a whim and soon forgotten, the details of the letter disappear while a woman tends a pharmacy, waiting for someone from long ago. Standing between them are six generations, a forgotten dream, and somewhere called home.

When Steve Hanna boards a plane for Madrid on what is supposed to be a normal study abroad trip, he has no idea where it is about to take him. From the first person he meets on the flight over to the last person he encounters in a small town pharmacy, a series of seemingly unconnected events begins to unfold. As Steve works his way across six countries to the heart of the Czech Republic, he ends up uncovering a larger narrative—a story six generations in the making. Long ago his ancestors paid a price and made a pact to set one person free. One hundred and twenty-five years later, their pact is about to be fulfilled.
