The J.K. Rowling book published online in daily instalments during 2020 was The Ickabog.
Rowling released the children’s fantasy story for free on a dedicated website between 26 May and 10 July 2020, during the COVID-19 pandemic. She had written the story years earlier while working on Harry Potter, then revised it for publication.
The Ickabog is set in the fictional kingdom of Cornucopia. Its plot concerns a legendary monster, political manipulation and the consequences of spreading fear. Rowling invited children to submit illustrations, and selected entries were included in the printed edition.
The book was published in print and digital formats on 10 November 2020, with proceeds supporting projects connected with the pandemic. It is distinct from The Christmas Pig, another children’s novel by Rowling, which was published in 2021. The Ickabog is also separate from the Harry Potter world.
