Par l'auteur de La fille du déménageur (éditions Livre de Poche Jeunesse et Black Moon nouvelles) et L'île des beaux lendemains (éditions Belfond.) Une jeune femme de 22 ans est retrouvée, presque morte, dans une chambre close de la pyramide de Khéops. A son côté repose la dépouille de son mari, un milliardaire américain. Un tatouage en croix orne le bas de son dos, dont Jessica Desroches-Prycene se rappelle pas l'origine. En fait, Jessica Desroches-Prycene se souvient de rien, si ce n'est de son prénom : Sixtine.

At the age of 83, retired butcher George Nicoleau is about to set off on the greatest adventure of his life. George and his neighbour Charles have long dreamt of a road trip, driving the 3500 kilometres that make up the stages of the Tour de France. And now that George's over-protective daughter has gone to South America, it's time to seize the moment. But just when he feels free of family ties, George's granddaughter Adèle starts calling him from London, and he finds himself promising to text her as he travels around France, although he doesn't even know how to use a mobile. George is plagued by doubts, health worries and an indifference to modern technology. And yet – might the journey still prove to be everything he had hoped for?
