When a sudden storm drives siblings Astra and Canis into their school counselor's office, they uncover the legendary Emotion Emergency Kit. Armed with Breathing Balm, Validation Bandages, and other magical tools, they embark on a spirited adventure through Anxiety Alley, Grief Grove, Frustration Falls, and beyond-helping friends navigate pre-test jitters, heartbreak, anger, and loneliness. As they apply the kit's soothing remedies, they teach their peers essential coping skills. By the final chapter, Astra and Canis transform their school into a caring community, erecting an Emotion First-Aid Station where everyone learns that tending to feelings is as vital as treating scrapes and bruises.
