Marek Emanuel Snarski, a resolute thirteen-year-old, doesn’t want to be a child anymore. He yearns to embark on a new stage in life – wouldn’t it be great to become an adult all in one go? This proves to be no easy task, so the boy decides to get himself some help. He starts by writing a blog. Then, from a mysterious magician he meets on the Internet, he buys some special adult pills. Unfortunately, the problems don’t go away; quite the contrary – they grow to monstrous proportions. A coming-of-age novel full of adventures. A wise message lies behind the fast action and humour. It is not about being an adult, but about being mature. Mark’s troubles only cease when he stops selfishly viewing the world as if it revolved around his bellybutton – when he observes that other people also need a little help and understanding sometimes.
