Nearly two months after Amazon announced the purchase of comiXology, the first title from the retail giant's Jet City Comics imprint has debuted on the digital comics platform.

Wool: The Graphic Novel, an adaptation of the bestselling sci-fi novel by Hugh Howey, will be serialized in six biweekly issues beginning today on comiXology for $2.99 each. The full run is also available for $4.99 on Amazon.com as a Kindle Serial, with new issues arriving on the same schedule; comiXology will offer a $4.99 bundle once all six installments have been released.

A dark, dystopian story set on a post-apocalyptic Earth, Wool was published in 2011 by Howey as a novelette through Amazon's Kindle Direct Publishing system. As it attracted a following, he wrote more installments, which became the bestselling Silo Series. The graphic novel is written by Jimmy Palmiotti and Justin Gray and illustrated by Jimmy Broxton; a print edition will be released in August.

Amazon launched its Jet City imprint in July 2013, intending to serialize its titles for the Kindle, and then offer bundled digital editions and print collections. Naturally with the acquisition of comiXology in April, the distribution channels expanded.
