The book description is basically all one needs know about this book. Wurlitzer is a fine writer and this book goes down pretty easily. Unfortunately (for "Drop Edge of Yonder," not me) I pretty recently read "The Sisters Brothers" which hit all the same beats this book did but better. Hatchet Jack and Delilah were really the only characters who held much interest for me with Zebulon's dad's single scene being a high point as well. I'm not angry with the time that I spent with "Yonder" but there wasn't much to recommend it either.
It's fine but on a list of like books, see the other sights first
