About the book:

Pete and the Persian Bottle is the story of nine-year-old Peter (Pete) Bartlett, an average boy, whose biggest wish is to stand out in a crowd, and not feel like the world’s biggest loser anymore.

While scavenging for go-cart parts in a rubbish skip, Pete comes across a curious looking bottle. When he opens the bottle, he releases a long-trapped genie. Eager to get his three wishes, Pete pushes the genie into making him special. The genie turns Pete into a rat. What will he do?
