Trust Exersise: For better or worse

It's probably best to think of Susan Choi's Trust Exercise as three short novels bound together by some elements in common - the first a story of teenage aspiring theater kids in an arts h.s., the 2nd a #MeToo story of attack and revenge, the 3rd a search for origins by an adopted daughter story - rather than as a single, coherent novel, as Choi makes some some totally weird decisions that make it needlessly difficult to accept this as a coherent work on its own. For example, why the random switch from first- to third-person, sometimes in mid-paragraph? Why build the dramatic conclusion on the around a character that we do not meet until 3/4 through the novel and who never really emerges as an individual? Why leave so much ambiguity about the endings of the 2nd and 3rd/final narrative movements? And why wouldn't there be any follow-up, at least within this novel, after the act of anticipated violence that conclusions section 2? So, in short, I'm being ambivalent here; it was easy to read the novel and it has some dramatic moments and some insight into the arts-school culture as best as I know it but on the other hand there's something that feels almost improvised about the plot and structure, as if the events and the characters, over a span of 30 years or so, emerge out of nowhere without adequate reference back to the established groundwork of the earlier narrative stages. It's worth reading, but at times I wanted to wake the author up or come at the pages with an editor's pen. Put another way, if this were an exercise in trusting the narrator, one of us would have, at some point, failed.
