Hold on to your sorting hat.
Bloomsbury is preparing two new books to join the Harry Potter pantheon, and they're both being published this year.
Admittedly, they are not JK Rowling novels, but tie-ins to accompany the British Library's exhibition of Harry Potter, which was first published 20 years ago this year.
The books are Harry Potter: A History of Magic - The Book of The Exhibition "which takes readers on a journey through the subjects studied at Hogwarts School of Witchcraft and Wizardry", Bloomsbury said. And Harry Potter - A Journey Through A History of Magic, "the history of magic, from alchemy to unicorns, ancient witchcraft to Hogwarts".
The news comes as the publisher reveals a jump in revenues of 19 per cent for the three months to 31 May, driven by its consumer division. Full year profits should be in line with expectations however, with Bloomsbury noting that the first quarter traditionally generates the smallest profit of the financial year.
Top selling titles in the quarter included A Court of Wings and Fury by Sarah J Maas, the Harry Potter series, Norse Mythology by Neil Gaiman,Tom Kerridge's Dopamine Diet and The Strange Death of Europe by Douglas Murray. Fantastically Great Women Who Changed the World by Kate Pankhurst is the biggest selling children's non-fiction title in the UK in the calendar year to 3 June, according to Nielsen BookScan.
The results for the six months ending 31 August will be announced on 23 October.
