Alone. Francis Tucket now feels more confident that he can handle almost anything. A year ago, on the wagon train, he was kidnapped from his family by a Pawnee hunting party. Then he escaped with the help of the mountain man, Mr. Grimes. Now that he and Mr. Grimes have parted ways, Francis is heading west on his Indian pony, crossing the endless prairie, trying to find his family.

After a year with Mr. Grimes, Francis has learned to live by the harsh code of the wilderness. He can cause a stampede, survive his own mistakes, and face up to desperadoes. But when he rescues a little girl and her younger brother, Francis takes on more than he bargained for.
