A little book for big feelings.

Informative and accessible, The Book of Knowing is a friendly, therapeutic guide for teens to understand and control their feelings. In 2015, clinical psychologist Gwendoline Smith began a Tumblr blog under the pseudonym Dr. Know. Her Gen Z-friendly approach to CBT (cognitive behavioral therapy) resonated, and the idea for this book was born.

With lively art, tangible advice, and immersive activities, this book is a handy guide for dealing with big feelings that provides humor, kindness, and manageable strategies for issues that can sometimes feel out of our control.
