The novel has two protagonists, Ben and Adrian. Adrian is a dual survivor of Hurricane Katrina and childhood sexual abuse. Her boyfriend Ben can’t make a decision about the future. So, one fears her past, the other fears his future. Then, a slave ship appears over their heads, and they have to figure out what to do. There’s a witch named Cut Mary, a doppelganger, ghosts, even a zombie. And a cat that has two origin stories. The Through also involves the town of Okahika, which I can best describe as a Southern ghost town. There’s one Okahika, but it exists simultaneously in every Southern state.
To be a bit less concrete, The Through is about the dissonance between the observable universe around us and the magical universe inside us. Sometimes those two realities fit together, and sometimes they don’t. Sometimes the observable and magical switch places. So in the book, we see the observable place in Northport, AL, and the magical place in Okahika, a.k.a. The Through, and characters who navigate both spaces.
