Harry Potter fans, who were left heartbroken following the end of Harry, Hermione and Ron with its last series - Harry Potter and the Deathly Hallows - can now cheer, as the muggle book lovers can now bid for the exclusive first edition of "Harry Potter and the Philosopher's Stone" annotated by the author, J. K. Rowling at a unique charity auction.

For those who wondered what went through J. K Rowling's mind while penning down the remarkable book, the charity auction to be held on 21 May at Sotheby's in London will be a great platform.

The book contains 43 pages of J.K Rowling's handwritten thoughts and commentary about the book and its film adaption according to English PEN organisation. Furthermore, the book will contain 22 hand-drawn illustrations by Rowling, including that of a baby Harry Potter sleeping and one of the legendary headmaster of Hogwarts, Albus Dumbledore.

"...I wrote the book...in snatched hours, in clattering cafes or in the dead of night. For me, the story of how I wrote Harry Potter and the Philosopher's Stone is written invisibly on every page, legible only to me. Sixteen years after it was published, the memories are as vivid as ever as I turn these pages," shares Rowling in the book.

The book to be auctioned at the charity auction - 'First Edition Second Thoughts' - will support English PEN organisation and Lumos Foundation. The Lumos Foundation founded by J. K Rowling supports the eight million children in institutions worldwide to regain their right to family life and to end the institutionalisation of children.

Besides Harry Potter, 'First Edition Second Thoughts' will put under hammer 50 contemporary first editions of books, annotated by their authors and all takings will benefit English PEN's core programmes to defend the freedom to write and the freedom to read.

A few of the books to be auctioned include Margaret Atwood's The Blind Assassin, John Banville's The Sea, Yann Martel's Life of Pi, Helen Fielding's Bridget Jones's Diary, Ian McEwan's Amsterdam, Michael Murpurgo's War Horse, and DBC Pierre's Vernon God Little.
