The ancient world saw many empires rise and fall. But how did massive empires such as Babylon or Rome move information and resources across continents? They relied on one of the oldest technologies in human history: transportation.

Ever since humans first began migrating within and outside of Africa, they have needed transportation technology to help move themselves and their possessions. Beginning with shoes to support feet over rough ground and boats to traverse water, humans quickly created a wide range of inventions to help them move faster and carry more over long distances.

From prehistoric hunting paths to the widespread highways of Rome, learn about the ancient transportation methods that shaped human history and paved the way for planes, trains, and superhighways.

La continuación de Escuadrón, la nueva saga épica de Brandon Sanderson.

Este es el segundo libro de una serie épica sobre una chica que guarda un secreto en un peligroso mundo en guerra por el futuro de la humanidad. En él continúan las aventuras de Spensa Nightshade, la joven piloto que ha conseguido un puesto en el escuadrón de defensa de la humanidad contra los ataques alienígenas.

En realidad, ella siempre quiso ser piloto: poder probar que es una heroína, como su padre. Y aunque llegó a lo más alto, los secretos que desenmascaró sobre su padre fueron aplastantes.

Los rumores sobre su cobardía resultaron ciertos. Abandonó su vuelo durante la batalla contra los Krell. Peor aún# se volvió contra su equipo y los atacó. Sin embargo, Spensa está segura de que hay aún más por descubrir en esa historia. Y, si es necesario, viajará hasta el fin de la galaxia para salvar a la humanidad.

ENGLISH DESCRIPTION

The #1 New York Times bestseller!

From the #1 New York Times bestselling author of the Reckoners series, Words of Radiance, the Mistborn trilogy, and the Stormlight Archive comes the second book in an epic series about a girl with a secret in a dangerous world at war for humanity's future.

All her life, Spensa has dreamed of becoming a pilot. Of proving she's a hero like her father. She made it to the sky, but the truths she learned about her father were crushing. The rumors of his cowardice are true--he deserted his flight during battle against the Krell. Worse, though, he turned against his team and attacked them.

Spensa is sure there's more to the story. And she's sure that whatever happened to her father in his starship could happen to her. When she made it outside the protective shell of her planet, she heard the stars--and it was terrifying. Everything Spensa has been taught about her world is a lie.

But Spensa also discovered a few other things about herself--and she'll travel to the end of the galaxy to save humankind if she needs to.
