BBC has announced "Class," a "Doctor Who" spinoff from YA author Patrick Ness which will take place in contemporary London as dangers start breaking through the walls of time and space. Described as "Coal Hill School and 'Doctor Who' like you’ve never seen them before," the new series will run for eight 45-minute episodes.

"I'm astounded and thrilled to be entering the 'Doctor Who' universe, which is as vast as time and space itself," said Ness. "There's so much room there for all kinds of amazing stories, and to work with Steven Moffat and Brian Minchin to find a place to tell one of my own has been an absolute joy. I can't wait for people to meet the heroes of 'Class,' to meet the all-new villains and aliens, to remember that the horrors of the darkest corners of existence are just about on par with having to pass your A-Levels."

“No one has documented the dark and exhilarating world of the teenager like Patrick Ness, and now we're bringing his brilliant story-telling into Doctor Who. This is growing up in modern Britain - but with monsters!” added "Doctor Who" showrunner Steven Moffat.

Ness, Moffatt and Brian Minchin will executive produce the project, which was commissioned by Damian Kavanagh, Controller BBC Three and Polly Hill, Controller BBC Drama Commissioning. No further details are known at this time.

"Class" will film in and around Wales in Spring 2016 and air next year. "Doctor Who" Series 9 starring Peter Capaldi as the Twelfth Doctor premiered September 19 on BBC.
