La finestra del temps

(en Catalán)

En Micah no entén perquè els seus pares els han arrossegat, a ell i els seus germans, a l’aventura esbojarrada de viure tot un any a milers de quilòmetres de casa seva. Però els problemes que tenen per adaptar-se a una nova llengua i a uns costums que els semblen marcians no seran res en comparació amb les peripècies que viuran quan descobreixin una ploma que permet viatjar en el temps i vagin a parar, sense saber-ho, al mig de la Guerra Civil.

A Sketch in Time

Micah struggles to adjust to living in Barcelona and going to school in a foreign language–who’s ever even heard of Catalan? But the difficulties of a year abroad are nothing compared to the adventure that begins when his younger sister and brother find an old pen that draws windows into the past. Micah and his siblings tumble into 1938 and into the dangers and deprivations of the Spanish Civil War.
