". . .The tone is incredibly consistent, providing a wonderfully coherent whole between these two writers, during the pandemic area. . .This is a book I wished I'd written; and I'm terribly jealous."
--Rob McLennan, Critic and author of Notes and Dispatches: essays

"If you asked me the genre of this book, I'm not sure I could give you a concrete answer. It seems unable to be boxed in, despite the blocked prose poetry. These collaborative page-long pieces are semi-autobiographical, magical, dipping into daydreams, worrying about the world, traveling back in time, reflecting and forgetting and rebuilding and growing. Not memoir, not a novel, not a poetry collection. The same body is occupied despite the two writers, who both seem to be channeling something larger than themselves. Like two minds inside of a solo ghost, floating around the globe, one fractured catastrophe at a time."
--Ben Niespodziany, Neonpajamas.

"Klahr Zeller frame [There is Only One Ghost in the World] in such a way that, even though the narrative follows no obvious trajectory, it captures, by the end, an arc of unabashed hope in the simplest joys."
--Shyanne Hamrick, Heavy Feather Review.
