Circus owner Nell Gifford will be making a special appearance at the White Horse Book Shop in Marlborough to celebrate the launch of a new book club.
The revamped book shop in High Street is donating money to Great Bedwyn Playgroup through a new loyalty card.
Children at the preschool can use the cards every time they shop there and five per cent of their purchase will be donated to the playgroup.
The book signing is on August 29 and Great Bedwyn Playgroup cardholders can meet Mrs Gifford at 10.30am. All families can join in at 11am.
