My entry to the Harry Potter series Contest, in the first contest - The Sorcerer's Stone. As this is the first contest, I started with the beginning - Harry entering the magical world for the first time. My entry is based in the book.
About this creation
"Doris Crockford shook Harry's hand one last time, and Hagrid led them through the bar and out in a small, walled courtyard, where there was nothing but a trash can and a few weeds.
He tapped the wall three times with his umbrella.
The brick he had touched quivered - it wriggled - in the middle, a small hole appeared - it grew wider and wider - a second later they were facing an archway large enough even for Hagrid, an archway onto a cobbled street that twisted and turned out of sight.
'Welcome,' said Hagrid, 'to Diagon Alley.'"
