The first volume will be subtitled 'Freefall' and collects issues #1-5 of Joss Whedon, Andrew Chambliss and Georges Jeanty's new title.
"Season 8 ended with a bang that cut the world off from magic - culminating in another set of world-ending problems," said the publisher.
"Buffy has left her best friend, Willow, powerless, and brought an end to a millennia-long tradition of superpowered girls. By day, Buffy is a twenty-something waitress with no real direction, and even though magic is gone, she's still a vampire slayer by night.
"Bigger problem? Vampires are becoming an epidemic... of zompires!"
Whedon promised a more "down to earth" theme for the new series, which launched in September following the conclusion of the Season Eight comics series, which followed on from his seven season television show.
Buffy the Vampire Slayer Season Nine volume one: Freefall will be released on August 1.
