The Lost Soul (Polish: Zgubiona Dusza) is a picture book written by Olga Tokarczuk and illustrated by Joanna Concejo.

The next day, John visits an old, wise doctor who tells him that the world is filled with people who have lost their souls, accidentally leaving them behind as they are unable to keep up with the pace of everyday life.

He buries his watches and suitcases in the garden, which then bloom into colorful flowers and large pumpkins and provide him with food for the following winters, and John and his soul live happily ever after.

[12] Twelve illustrations from the book that presented a “moving story about waiting, patience, and mindfulness” were displayed at the Wyspiański Pavilion in Krakow, Poland, from February 15 until March 9.

[13] Concejo's illustrations and Tokarczuk's sketchbooks were on display at Dom Słów, The House of Words, in Lublin, Poland, from October 5 until November 5.
