While her mood mirrors the kite's motions - gently rising, twisting in the wind, tangling in a tree, and crashing to the ground - the pair continue to try. Despite the ups and downs, their love is, and will always remain, constant. "Is today a kite day?" I ask Mamuś.Her smile is a blossom unfolding."Let's go and see," she says.An honest yet hopeful glimpse into a child's experience with a parent who has bipolar illness or other mood-related struggles, including concrete suggestions for young readers who are concerned about a loved one, this is a key social and emotional learning (SEL) book for young readers and loved ones navigating a mental health illness.
