'Harry Potter and the Chamber of Secrets' gets Hogwarts House editions on 20th anniversary

After "Harry Potter and the Philosopher's Stone", the second book of the series, "Harry Potter and the Chamber of Secrets", has also received new Hogwarts House-themed covers on its 20th anniversary.

The book, which was first published on July 2, 1998, got new covers illustrated by Levi Pinfold featuring an interpretation of the door to the Chamber of Secrets "with beautiful iconography and features woven in to the design that are particular to that house".

The new books will be available in hardback and paperback editions.

"The hardbacks are in each house colour with artwork in black and striped sprayed edges. The paperbacks are black with artwork in the corresponding house colours. Both editions contain additional content including an illustration of the house common room by Levi Pinfold, a house introduction and a mini-feature on house-elves," Bloomsbury said in a statement.

The "Harry Potter and the Chamber of Secrets" continued Harry Potter's adventures at Hogwarts.

It introduced some of the most-loved characters from the wizarding world, including Dobby, the house-elf.

Last year's House editions of "Harry Potter and the Philosopher's Stone" received great response from fans.

"Overall sales of Harry Potter books were up by more than 50 per cent in 2017 and the entire series has now sold over 500 million copies worldwide" the publishers said.

Bloomsbury will also publish House editions of the remaining five books in the Harry Potter series.
