Lex decides to enter the forest for the first time and discover all the secrets that are hidden in it. Apart from new places, events and creatures, Lex, accompanied by his oak tree friend, explores personal limitations, causes of behaviors, interactions with the environment and people around him, the value of respect in these interactions and, most importantly, the meaning of freedom, which is the central subject of the book. Their roaming is a course towards adulthood and independence through questioning, healthy disobedience and critical thinking. Although the story gives the chance for a deeper level of interpretation for older children, it remains a fun and adventurous read for all ages. Without being heavy or instructional, the book's main goal is to trigger critical thought and constructive conversations; to let Lex's discoveries during his roaming be perceived in a free and personal way by each reader. To inspire children who are just taking their first steps in life with the joy of spreading their own wings and taking their future into their own hands, and also to remind older readers of the excitement of constant exploration, one of the most important ingredients in a joyful life.
