Recently a friend of mine has introduced Terry Pratchett's Discworld series of books. Terry Pratchett is both a hugely popular and critically acclaimed author from England. He has sold over 70 million books, has been appointed as an Officer of the Order of the British Empire for his continued service to literature, and even holds the title for most shoplifted author.
Discworld takes place in a flat fantasy world balanced on the back of four giant elephants who are themselves carried on the back of a giant turtle. It combines elements of fantasy, comedy, satire, and science fiction to provide an unique experience. If you are looking for a something refreshing to read I recommend that you give this series a try. From the first book The Color Of Magic, to the upcoming 37th book, I shall Wear Midnight, Terry Pratchett has provided a huge world to be explored.
