British book retailer Waterstone's is hoping to set up a helpline for distressed fans of the popular Harry Potter series because two characters will be killed off in the final instalment, The Daily Telegraph reported. "This could be a similar moment to when (pop band) Take That split up -- there could be a lot of upset teenagers out there," said Debbie Williams, a buyer for the book chain.
"We are looking to set up a helpline for them."
Waterstone's predicts that half a million copies will fly off the shelves when the seventh and final edition of British author J.K. Rowling's hugely successful Harry Potter series -- "Harry Potter and the Deathly Hallows" -- becomes available on July 21.
Rowling has said she is poised to kill off two characters in the final instalment and many fans fear that Harry, in his last year at Hogwarts school, will be one of the victims.
The Harry Potter books have sold 325 million copies worldwide and have been translated into 64 languages, as well as being converted into a successful film franchise starring Daniel Radcliffe.
The books have made Rowling an estimated one billion dollars.
The fifth movie in the series is due for release about one week before the final book is released.
