Let's take a look at the new details which have been revealed since the announcement of the project:
According to Pottermore, a treasure trove of information for all things Harry Potter, the story will center around Harry and his son, Albus Severus, 19 years after the events of Harry Potter and the Deathly Hallows.
Fans will remember that Harry marries Ginny Weasley and has 3 kids, James Sirius, Albus Severus, and Lily Luna. At the end of book 7, Harry sends James and Albus off to Hogwarts, and all is well.
Here's the official synopsis from Pottermore:
"It was always difficult being Harry Potter and it isn’t much easier now that he is an overworked employee of the Ministry of Magic, a husband and father of 3 school-age children.
"While Harry grapples with a past that refuses to stay where it belongs, his youngest son Albus must struggle with the weight of a family legacy he never wanted. As past and present fuse ominously, both father and son learn the uncomfortable truth: sometimes, darkness comes from unexpected places."
Here's the official artwork, showing a sad young boy seated inside what looks like a straw version of a Golden Snitch, that special ball that wizards and witches use to play Quidditch.
