John Shirley has penned several books expanding the universes of video games, including BioShock and Borderlands. Now he is writing an eBook to release alongside Watch Dogs.

Watch Dogs //n/Dark Clouds is picking up where the Watch Dog video game leaves off, but it is a standalone story, so it is not necessary to play the game to read it. The eBook is available in two formats: a standard one, and an interactive format with videos and pictures. The video description for Dark Clouds’ announcement trailer states that the book will be available both as an eBook and as an app on mobile devices.

Watch Dogs //n/Dark Clouds is releasing on May 27, along with the game, and will be available in English, French, Italian, German, and Spanish. For more on Watch Dogs, check out a recent hands-on preview.  

Watch Dogs is coming to PlayStation 4, PS3, Xbox One, 360, PC, and Wii U, though the Wii U version is launching at a later time.
