JK SAYS BEWARE OF THE HARRY ROTTERS; Fears of spoilers.
AUTHOR JK Rowling has warned Harry Potter fans to guard against spoilers on the plot of the last book.
JK said Harry Potter And The Deathly Hallows - due out on July 21 - would be a target for "sad individuals who get their kicks from ruining other people's fun".
The novel is the seventh and final one in the Harry Potter series.
Speculation has been rife the boy wizard will be killed off but JK hopes the ending will be a secret until fans read it for themselves.
The Perthshire-based writer said on her website: "We're a little under three months away now and the first distant rumblings of the weirdness that usually precedes a Harry Potter publication can be heard on the horizon.
"I want the readers who have grown up with Harry to embark on the last adventure they will share with him without knowing where they are they going."
She said there would be some who would claim spoilers were "part of the hype" and that she was trying to protect sales, not readers.
But JK insisted: "Spoilers won't stop people buying the book, they never have. All it will do is diminish their pleasure in the book."
The writer praised the work of fan site Leaky Cauldron in trying to protect the integrity of the books.
She said: There will always be sad individuals who get their kicks from ruining other people's fun but while sites like Leaky take such an active stance against them, we may yet win."
JK has already admitted that she is "simultaneously heartbroken and euphoric" over finishing the last Harry Potter book.
And she admitted Deathly Hallows was her favourite of the books - which is the "most wonderful way to finish the series".
JK MARKED her completion of the Deathly Hallows by signing a marble bust in the hotel room in The Balmoral in Edinburgh, where she finished writing it.
She wrote in black marker pen: "JK Rowling finished writing Harry Potter and the Deathly Hallows in this room (652) on 11th Jan 2007."
