First off, this is an interesting 1960 period piece that describes a carnival sideshow. Strong writing at the scene and set-piece chapter level, but the overall structure is a real mess. A lot of skipping around and after the fact explaining that detracts from the narrative's through-line.
The bigger problem comes at the beginning: Why does Katie go out for a beer with the carni Ernie? And then after he rapes her she tells him to marry her and take her on the road with him? That made no sense and nothing in the text really supported her actions. So it's just a plot point to be quickly dispensed with because the story is Katie on the road with Ernie as he runs his scammy sideshow.
Stuck with this one because the writing was good and it was a carnival novel I had been curious about, but the structure and the unbelievable-ness of the Katie's motivations probably would have had me leaving this one unfinished otherwise.
