Reach for this book when you notice your child is acting unusually anxious, defensive, or physically weighed down by a secret they are afraid to share. This classic story follows a young boy who tells a small lie about eating a cookie, only to watch that lie manifest into a physical, green monster that follows him everywhere, growing larger and more obnoxious with every passing second. It brilliantly externalizes the internal sensation of guilt and anxiety, making it a perfect tool for children ages 4 to 8. Parents will find this book an invaluable resource for discussing the heavy burden of dishonesty and the immense relief that comes with telling the truth, even when the truth is difficult to say.
The book deals with moral development and guilt. The approach is entirely metaphorical (the lie as a physical monster) and secular. The resolution is realistic and hopeful, showing that while confession is hard, it leads to immediate emotional relief.

This book can be read cold. Parents should be ready to reassure the child that everyone makes mistakes and the 'monster' can always be shrunken down by being honest. A parent who has just caught their child in a circular lie or has noticed the child is being unusually clingy or irritable after a suspected misbehavior.
Younger children (4-5) will focus on the silly, pesky nature of the monster and its physical growth. Older children (7-8) will more clearly grasp the metaphor of internal guilt and the psychological weight of secrets.
Unlike many books that focus on the punishment of lying, this one focuses on the internal discomfort of the liar. It treats the lie as an external entity that the child has the power to banish, which is an empowering perspective for a child feeling stuck in a lie.
A young boy tells a lie to his parents about eating a cookie. Almost immediately, a small, green, ghost-like creature appears. As the boy tries to ignore or justify the lie, the creature grows larger, noisier, and more intrusive, literally sitting on him and following him to bed. The boy realizes the monster will never leave unless he tells the truth. Once he confesses, the monster shrinks and eventually vanishes.
