A portal in time, and suddenly the world changes! Boston was just at the Arab silk market in Granada with his classmates. Suddenly, everything is different: through a portal in time, Boston has landed in the year 1492. There, things become life-threatening for him. He arouses suspicion at the Spanish royal court, and in the Alhambra, he falls into the cruel clutches of the Inquisition. However, two new friends, Tariq and Salomon, who are themselves threatened as a Muslim and a Jew, support him in this seemingly hopeless situation. But Boston's return depends not only on finding the key to the present but also on the discovery of America. A great novel by Kirsten Boie - gripping, thrilling, and fascinating until the last page.
