In Between Twilight Post delves deep into the difficult journeys of everyday life and intersects those with the difficult maps of the past. There are "atrocities in the body" and many ways a person can falter, fall or rise from "the hue of an unseen self." Post explores the necessary truths, the ones we can no longer hide, the ones we've held on to, for too long. In these poems, the reader will more fully understand Faulkner's "the past is never the past in never past, it's not even dead." The poet infuses elements of evolution, illness, astronomy, humanity, internal travels inside our bodies, and travels back in time "before shadows understood their first for light." Post's poems will seep into our subconscious and help us see how a room can be "dark and iridescent all at once."
