Many people compare depression to an abyss - a never-ending downward spiral of hopelessness. In this heavy but empowering follow-up to the best-selling "Get Out of Your Head: A Toolkit for Living with and Overcoming Anxiety," author Brian Sachetta takes that comparison literally, bringing readers on an aquatic adventure through one of life's most difficult challenges.

On that journey, Sachetta explores the biological, psychological, and social forces behind the affliction to help readers understand how it often manifests in their lives. And, most importantly, he provides a beacon of hope to those stranded at sea or caught in the whirlpool of despair.

It's one mental health voyage you won't want to miss.
