The first book review of Harry Potter and the Cursed Child will be written by a 10-year-old speed-reading prodigy from Wheathampstead.

Toby L'Estrange aims to post his critique of the new play shortly after its midnight release on Sunday.

The schoolboy can read an average 400-page book in under two hours using techniques he learnt from his grandmother Susan Norman, a speed-reading expert.

Toby will have the latest instalment of the Harry Potter stories delivered direct to his Amazon Kindle just after midnight on Sunday morning.

He will immediately start speed-reading at a rate of 1,000 words per minute.

He said: "Harry Potter and reading are my two favourite things so to be able to combine them is a dream come true.

"My little brother Harry is pretty jealous, but he will be able to read all about it in my review which I hope will be the fastest one posted to Amazon."

Toby added: "I have been practising loads on my Kindle and am confident I can be the fastest reviewer, although I promise not to give away any spoilers."

A self-confessed super-fan, Toby had read all the Harry Potter books by the age of eight and can recite all the spells used in the stories.

He will go to bed early on Saturday and set his alarm for just before midnight so he is ready when the book becomes available.

Harry Potter And The Cursed Child Parts One and Two is the script of the Harry Potter And The Cursed Child stage play.

Written by Jack Thorne, the play is from an original idea by Potter author JK Rowling and is directed by John Tiffany.

Set 19 years after the final novel - Harry Potter and the Deathly Hallows ended - the Cursed Child Parts I and II features Harry, now a father of three and his battle with the past.

His son Albus and old Hogwarts chums Hermione and Ron also take centre stage in the sell out play that has won rave reviews from critics.
