Netflix recently branched out into comic books, and now it's dipping its toe into the world of book publishing. It's teamed up with Penguin Random House to produce a series of novels set in the same universe as its hit show Stranger Things.
One of the series will be a prequel about Eleven's mum and her involvement in the real CIA experiment Project MKUltra.
Before that will come a companion book to the series, called Stranger Things: World Turned Upside Down, as well as a young adult gift book. The prequel novel – written by Gwenda Bond of the Lois Lane trilogy – will launch next year.
It will feature a college student named Terry Ives, who was subjected to horrific experiments when pregnant with her daughter Jane (aka Eleven). These experiments left Eleven with supernatural powers.
Terry lost her child, and when she tried to recover her, was captured and turned catatonic from severe electroshock therapy. Terry featured briefly in the second series of Stranger Things.
The third series of the show won't arrive until next year, so these books should go some way to tiding fans over.
