The Princess and the Fog by Lloyd Jones
In this hilariously illustrated book, a young princess is living the life of any ordinary child until one day, a mysterious "fog" settles upon her, taking over her day-to-day routine and overhauling everything she used to enjoy doing. Suddenly, the princess begins to feel incredibly lonesome in her sadness. Although her parents and friends try to comfort her, nothing seems to work. That is, until one day, when her friend asks if she wants to talk. She learns that by reaching out for support from her family and friends, she is able to find activities that make her feel better and pull her out from the fog. I love that this story provides such a community-based approach to healing and coping with mental and emotional challenges, such as depression. The fun imagery also makes the sensitive nature of this book much more engaging, light, and relatable for young readers.
