How does the author use foreshadowing in Mr. and Mrs. Bo Jo Jones?

Foreshadowing is not employed in the novel, as the authors uses a subtle but powerful technique to make July more realistic. This technique is centered around the immediacy with which the author relates certain important events. July's decision to have sex, decision to get married, death of her baby, and several other more minor events come suddenly and without warning or build-up in the narrative. This, along with the aforementioned mimicking of a young girl's thought process, makes the novel feel less like an "authored" fiction and more like a real young girl recounting her story, a girl who may not be familiar with the usual rules of suspense or build-up that a novelist might usually employ to achieve maximum effect or impact.
