Avatar: The Renegade Collective-Book 1: Convictions
13 parts Complete The Hundred Year War is still going on. Among the Fire Nation is young Ezra Bridger, an orphan who's parents were killed 10 years ago. He is sent to find prince in exile Zuko, who was last seen near the North Pole.
All the while, young waterbending protege, Sabine Wren, is being sent alongside a team of waterbenders to check up on the Southern Water Tribe. But after being told something she'd rather die then hear, she jumps ship and leaves.
Meanwhile, earthbending freedom fighters Kanan Jarrus, Hera Syndulla-Jarrus, and their child, alongside non-bender Zeb Orrelios, are looking to keep the Fire Nation away from their home.
Destiny has set things in motion that cannot be undone. Soon, these few will meet and when they do, the results will be... interesting.
