Dark Horse is kicking off a brand new adult coloring book program this fall with Avatar: The Last Airbender and Serenity.

Each of these coloring books will feature forty-five pages of original artwork created specifically to be colored on thick, heavyweight 10 x 10 inch pages.

You will be able to relive your favorite scenes from Avatar: The Last Airbender with original black and white illustrations by artist Jed Henry in collaboration with creators Michael Dante DiMartino and Bryan Konietzko.

The Serenity Adult Coloring Book allows you to adventure through the ‘verse as you relive your favorite moments from the Firefly series and more.

Dark Horse plans to announce more coloring books in the ensuing months.
