A signed copy of the fifth adventure of Harry Potter is being put under the hammer - three months before the book goes on sale.
JK Rowling will write seven Harry Potter books
JK Rowling's Harry Potter and the Order of the Phoenix is being sold in an internet auction to raise money for charity.
But the successful bidder for the story about the boy wizard will have to wait until the book is released in 21 June to collect their lot.
Bidding is open for 10 days on the e-Bay internet auction site, with all money going to the deaf-blind charity Sense.
Paul Amadi, director of fund-raising at Sense, said: "It is extremely exciting for Sense to be offered a signed copy of Harry Potter and the Order of the Phoenix which JK Rowling has promised to charity.
"This is bound to cause a stir among Harry Potter enthusiasts and book collectors."
The anticipation for the next instalment of Harry Potter's adventures has led it to become the one of the fastest bestsellers of all time, even before its release.
Shops and internet booksellers have been taking advance orders since the date of release was announced.
When the fourth book, Harry Potter and the Goblet of Fire, was published two-and-a-half years ago shops held midnight openings to meet the demand of excited fans.
So far more than 195 million copies of the Harry Potter series have been sold and the films of the first two books topped box offices around the globe.
