I was taught to read early and I'm mad about
books. My favourite author is Philip Pullman. He
is a remarkable contemporary writer. Philip
Pullman is a master of many genres. He has
written historical fiction, horror stories, fairy
tales, and fantasy fiction. Pullman is very
imaginative. He uses his vivid imagination to
develop fabulous plots. Philip Pullman uses very
rich, inventive language. He creates and
explores his own wonderful fantasy worlds. I
particularly enjoy Philip Pullman's Dark
Materials. They are really clever because they
are based on scientific ideas. I enjoy reading his
historical thrillers which are set in Victorian
England and present the adventures of Sally
Lockhart, a brave and clever young woman.
Philip Pullman's books have everything:
suspense, drama, action, and they are really fun
to read. His books are so suspenseful that you
can't stop
reading. And the characters are great. I
encourage everyone to read his books. I was
happy to learn that he was chosen as the Astrid
Lindgren Memorial Award
winner in 2005.
