Using the confluence of rivers in Pittsburgh as a metaphorical lens, Allegheny, Monongahela probes the ruinous misalignment between the external and internal lives of two sisters and their childhood in Western Pennsylvania. Their complex and difficult relationship is the spine of the collection, told obliquely through a series of sonnets and ekphrastic meditations on the paintings of Georgia O'Keeffe: the ways in which they separately navigate a violent family history that reverberates through their present and futures; their polarized impulses toward creativity and self-destruction. Rooted in a mutable, watery landscape that is not consistently recognizable, Allegheny, Monongahela investigates the collisions between the world and the self, the fissured identities that result, and the ways in which art may heal or fail to heal the cracks.
