A critically acclaimed debut novel praised as "unbearably poignant and beautifully told" (Eimear McBride), this captivating story follows a misfit man who adopts a misfit dog.

It is springtime, and two outcasts--a man ignored, even shunned by his village, and the one-eyed dog he takes into his quiet, tightly shuttered life--find each other, by accident or fate, and forge an unlikely connection. As their friendship grows, their small seaside town falsely perceives menace where there is only mishap--and the duo must take to the road.

Gorgeously written in poetic and mesmerizing prose, Spill Simmer Falter Wither is one of those rare stories that utterly and completely imagines its way into a life most of us would never see. It transforms us in our understanding not only of the world, but also of ourselves.
