Translate the text into English. The main characters of the series will be a group of slaves planning a bold escape from a Georgia plantation. On the road to freedom, they will have to cross 600 miles, find loyal friends—a pair of secret abolitionists who founded a station of the Underground Railroad, and also confront dangerous enemies—those who earn their living by hunting fugitive slaves, and it does not matter in what condition the slaves will be returned to their owners, alive or dead.
