Three years after life got in the way of their long-distance relationship, Californian illustrator Zoe and English engineer Martin have an unexpected opportunity to reunite- a second chance to follow in the footsteps of pilgrims in Europe. This time, they won't be walking the famous Camino de Santiago to north-west Spain but the less-travelled Chemin d'Assise and Via Francigena to Rome, the mountainous path down from rural France. And rather than each setting off solo, they will accompany Zoe's old friend Camille-who, despite her terminal illness, insists she will walk the whole sixteen hundred kilometres to seek an audience with the Pope-and her not-so-ex-husband, Gilbert, who sees the trip as a gourmet tour. Then Bernhard, Martin's young nemesis from the previous trek, shows up, along with Martin's daughter, Sarah, who is having a quarter-life crisis and doesn't exactly hit it off with Zoe.
