Nomad holiday that hasn't been celebrated in over one hundred years, but when cryptic visits from the spirit of Avatar Yangchen lead Aang to a refinery operating on land sacred to the Airbenders--they soon find themselves in peril as a dangerously powerful ancient spirit awakens with vengeance and destruction on its mind!

This collection of The Rift Parts 1-3 features annotations by Eisner Award-winning writer Gene Luen Yang (American Born Chinese) and artists Gurihiru (Thor and the Warriors Four), with a brand-new sketchbook section!
