Since the beginning of time, humans have wondered what lay beyond the horizon. The bravest left their homes and set out into the unknown. But how did they find their way? How did they travel? How did they survive harsh weather, hunger, and other terrible dangers? Starting in 340 BC with Pytheas the Greek, who sailed to the Arctic Circle without so much as a compass, and ending in 1969 when the crew of Apollo 11 landed on the moon, author Stewart Ross and artist Stephen Biesty take readers on an adventure to learn more about these brave explorers. Using vivid storytelling and dynamic unfolding cutaways and cross sections, Into the Unknown creates an experience for readers that is as exciting as exploration itself. - Jacket flap.
