In 1587 John White was chosen by Sir Walter Raleigh to lead a new colony at Roanoke off the Atlantic coast. After bringing many men, women, and children to the new land, White went back to England to gather supplies for the long winter. But when he finally returned to the fort almost three years later, he found that all of the colonists had vanished.

The only signs of life left were the letters CRO carved into a tree and the word CROATOAN carved into one of the fort's posts. Did the Spanish army capture the colonists? Did the colonists get in a battle with the native people--or join them? Did they try to follow John White to England and get lost at sea?
