The Adventures of Luna Mesa: Saying Goodbye is a tender children's story that helps families talk about grief with honesty and hope. When Luna and her siblings face loss, they discover gentle ways to remember, share, and carry love forward. Through beautifully illustrated chapters and hands-on activities, children learn to create a memory capsule, stitch a quilt square, and draw their invisible backpack of feelings. Each metaphor gives young readers a simple and concrete way to understand loss. This book helps children ages six to ten explore grief safely and openly, while also guiding families to create rituals of remembrance together. Parents and caregivers will find language that is honest, clear, and protective. Educators and counselors can use the story to introduce grief literacy in classrooms and groups. Created by Claudia L. Gatica, MSP, CLC, with a background in clinical psychology and two decades of experience supporting families, this story is both psychologically safe and deeply comforting. The Adventures of Luna Mesa is a series designed to help children and families explore big feelings together. Look for Book Two: When Things Change.
