Fans rave about Fifty Shades of Grey author EL James' new erotic novel 'Grey'
Eager readers have got their hands on the latest instalment of EL James' sadomasochistic Fifty Shades Of Grey saga after it was published on Kindle before bookshops opened.
The new book, called Grey, is a re-telling of the first novel in the hit series about an affair between mysterious tycoon Christian Grey and lover Anastasia Steele from the point of view of its title character.
Fans tweeted their joy at getting their hands on the book early.
Sarah Thomson said: "Started reading Grey soon as it downloaded - don't see much sleep for me tonight."
And Sarah Roche tweeted: "I'll be awake all night reading on the Kindle."
Meanwhile, fellow erotic novelists joined in as they ploughed through the plot.
Divas writer Rebecca Chance tweeted: "Stay with me twitter people as I live tweet Grey! It's already epic."
Wendy Leigh said: "EL James am 10% into Grey & love the intimate close-up perspective on the real Christian Grey."
A review for the Daily Mirror said "there's absolutely nothing vanilla about this book."
The story, set over the course of a month from May 9, 2011, to June 9, 2011, is described as "a fresh perspective on the love story that has enthralled millions of readers around the world" and the story of the title character's battle with the "compulsion to control" and "dark sexual desires".
It is dedicated by James to her readers with the words: "Thank you for all that you've done for me. You rock my world every day."
Among the acknowledgments are thanks to different people for help guiding the author through "an education in soil science", "behavioural health" and "guidance in flying a helicopter".
The book starts with the title character having a nightmare about his childhood before he meets Steele who is described as "a whirl of long chestnut hair, pale limbs and brown boots".
The story of Grey's pursuit of Steele and James' raunchy description of their S&M relationship will be familiar to readers of her first three books who are likely to make this one a worldwide best-seller as well.
It made headlines last week ahead of its publication today when it was reported a finished copy had been stolen.
The publishers vowed to continue to investigate the theft of a copy of the unpublished book despite police saying there was "no evidence" a crime was committed.
The hype surrounding the book will ensure copies fly off the shelves and its author is in New York as part of an international publicity campaign for the book which is a guaranteed best-seller.
Jamie Dornan played Grey and Dakota Johnson was his lover in the hugely successful film version of the story.
The Fifty Shades trilogy - Fifty Shades Of Grey, Fifty Shades Darker and Fifty Shades Freed - has sold more than 125 million copies around the world.
It has made James a millionaire many times over. This year's Sunday Times Rich List estimated her fortune at £75 million.
