I am in a rush so I am just going to quote TLC‘s news article:

Waterstone’s has launched a contest asking the public to submit their own stories. Winners of this event, two adults and one child from the Waterstones.com and store entries, will also appear in a postcard book alongside the authors’ stories. This book will be available for purchase later this year, with proceeds of the sales to benefit Dyslexia Action and English PEN as well.

To enter this contest, click here to download a postcard template to do at home, or use the online form. …  In addition to being published in the special book, “the national winners aged over 18 will also win an Arvon Writing Course and winners under 18 will receive �£500 of Waterstone’s voucher.”�

Good Luck to all who enter!
