The book of Peter Glocko, that has an artistic value, is based with ease on source of folk literature. The greatest treasure of the Slovaks is a spiritual heritage of legends, fairy tales, proverbs, and sayings. The book enriches fantasy and vocabulary of the young readers, and it develops their playfulness and creativity. It draws them into a complicated process of independent reading. In accordance with the manuscript, there is also a high artistic value of Martin Kellenberger's illustrations. Lucky is a pilgrim and he travels with a little falcon Tiny Eye across the fairy tale land. The hero listens to the people, from which he can learn something. In their narration, the writer elegantly joins the traditions, wisdom sayings, and folk literature. Surprisingly, and also likeably, the anti hero, Evil the Plaque's servant and a helper Stumblebum, is a comic character. Peter Glocko has added the third dimension to it as well by using sometimes non-standard Slovak language. The main goal of Lucky in not to fight with Evil the Plague, but particularly to search, i.e. directly for "the greatest treasure in the world". The book was awarded The Most Beautiful Children's Book of the Autumn 2016.
