A book of poems and painted images.

The poetic writing and images of Alicia Wirt-Fox's The Obscure Substance of Sky are divided into three parts. Each attempts to evoke three distinct realms. "The Obscure" pertains to the hidden, unseen, or arduous aspects of living in ourselves in the world as humans. "Substance" describes our material existence-discoveries in nature, in the body, or experiences on and of Earth. "Of Sky" alludes to immaterial realms, abstractions, and the world above. All the sections weave ideas and experiences, and the character of birds dance between each distinct space.
