When Dad came home, he brought something back with him, a dragon. Sometimes it's quiet. Sometimes it roars. But no matter what, Dad and his son learn that love can live right beside the hardest battles we fight. The Dragon That Visits Dad is a heartfelt children's story about family, understanding, and the invisible dragons that follow us home. Written by John Mercer, this tender, watercolor-illustrated book helps children make sense of big emotions, showing that love, patience, and connection can calm even the loudest dragons. Perfect for families healing after trauma, veterans and first responders, or anyone who wants to help kids understand emotional health with honesty and hope.
