A one-of-a-kind collection of 14 signed novels - all of them recent bestsellers such as Zadie Smith's White Teeth, Zoe Heller's Notes On A Scandal and Nick Hornby's How To Be Good - is to be auctioned online for charity by AbeBooks.co.uk and Penguin.

Penguin is reissuing 36 bestsellers in its famous retro striped cover designs on September 6 and has partnered with AbeBooks.co.uk to auction 14 signed copies of the modern fiction books from its 'Celebrations' series with all proceeds going to English PEN.

The auction, conducted on AbeBooks.co.uk, begins on Thursday 6 September and concludes on Tuesday 11 September at 6pm GMT. The unique collection of signed books, which are being offered in a single lot, will not be available again.
