Gene Yang blew our minds with American Born Chinese and Boxers & Saints — not to mention the Avatar: The Last Airbender comic. So we're thrilled to be able to premiere the book trailer for his new graphic novel The Shadow Hero, exclusively at io9. It's the origin story of an Asian American superhero from the 1930s.

Check out the trailer above, and here's the official description of Shadow Hero:

In the comics boom of the 1940s, a legend was born: the Green Turtle. He solved crimes and fought injustice just like the other comics characters. But this mysterious masked crusader was hiding something more than your run-of-the-mill secret identity... The Green Turtle was the first Asian American super hero.

The comic had a short run before lapsing into obscurity, but the acclaimed author of American Born Chinese, Gene Luen Yang, has finally revived this character in Shadow Hero, a new graphic novel that creates an origin story for the Green Turtle.

With artwork by Sonny Liew, this gorgeous, funny comics adventure for teens is a new spin on the long, rich tradition of American comics lore.

And here's the official bios of both creators:
