This collection addresses issues of identity as two people find themselves living in an uncommon landscape. Through hybrid narrative prose poems, Hank and an unnamed narrator try to navigate their relationship and understand their identities amid a landscape that offers them almost nothing. The continent at first seems empty, but something emerges in the vacuum of Antarctica. The narrator's gender skips and changes, and the characters' self-awareness grows into a sort of horror. Dennis James Sweeney's poems consider the fullness of emptiness, revealing attempts to love and grow when surrounded by a white and frigid landscape that seems to go on forever. The space of these poems is something beyond the Antarctic of scientific exploration, the icy outpost that has served for so long as a masculine proving ground for polar explorers. This is the Antarctica of domestic disharmony, of love amid loneliness, where two people encounter themselves in the changeless breadth at the end of the world. In the Antarctic Circle is the winner of the Autumn House Press 2020 Rising Writer Prize in Poetry.
