About the book: 1990 / In the 13th century, the Chinese expedition of Tokhtai and Li discovered America. Patrolmen Everard and Sandoval received a task from the Danellians - creatures from the distant future, the true masters of the Time Patrol - to organize the failure of the expedition. Otherwise, it may turn out that the Mongols will take over America and history will take a different path. The patrol killed the horses, burned the expedition's ships and forced its members to settle in America forever..
