Heart and Brain return with over sixty brand-new, never-before-seen comics in this riotous collection by a New York Times–bestselling author.

Vigorously demanded and highly anticipated, Heart and Brain: Gut Instincts is the follow-up to the tremendously popular New York Times bestseller, Heart and Brain: An Awkward Yeti Collection.

The Awkward Yeti’s Heart and Brain comics perfectly illustrate the ongoing, internal struggle betwixt head and heart.

Heart and Brain: Gut Instincts features the same lovable characters as the first book and introduces a host of other vital organs like insatiable Tongue, irritable Bowels, and abused Stomach.

Perfect for fans of Poorly Drawn Lines, Liz Climo, Randall Munroe, and The Oatmeal.
