The Hork-Bajir Chronicles (Animorphs Special Edition)
Description
In a time before their invasion of Earth, the Yeerks attacked a gentle and docile species known as the Hork-Bajir. This is the story of that battle. It was the battle that sent one Andalite war prince to crash land on Earth, where he would give five kids the power to morph, and become Animorphs. - from Amzon
