A 10-year-old speed-reading prodigy has finished the new Harry Potter story, Harry Potter And The Cursed Child Parts One and Two, in just 59 minutes - and gave it six out of 10 in his review.
Toby L'Estrange, from Wheathampstead, Hertfordshire, was challenged by Amazon to produce the first review of the new Potter story.
The schoolboy can read an average 400-page book in under two hours, using techniques he learned from his grandmother Susan Norman, a speed-reading expert.
The latest instalment of the Harry Potter stories is the script of a new original story by JK Rowling, John Tiffany and Jack Thorne.
The London-based play officially opened on Saturday night in the West End to coincide with the release.
Toby had his copy delivered direct to his Amazon Kindle by pre-order just after midnight on Sunday morning, and finished the book only 59 minutes after it automatically downloaded.
His review will be read by Amazon customers whether they are shopping on the website or on their Kindle.
The self-confessed superfan had read all the Harry Potter books by the age of eight and is able to recite all the spells used in the stories.
The youngster said: "It's a really good story.
"It's a very complicated story. It happens in different times, so it's really helpful if you know all the other books and characters quite well (I do - and so does any other true Harry Potter fan).
"When I first started it was really difficult to know what was happening because everything was mixed up, but then it all got quite exciting - and a bit (a bit!) clearer.
"It's mostly about Albus Potter and Scorpius Malfoy - which is odd because Harry and Draco were enemies. And Harry and Albus don't see eye to eye on - well, pretty much everything."
Adding that he did not have a favourite character, he said fans would need to read the book themselves to find out more.
"And I think you're going to love it," he said.
