In FRITO LAY, Beverly-Whittemore, as she did in BITTERSWEET, uses the perspective of a less affluent and less worldly protagonist to explore power dynamics, romantic entanglements, and the peculiarities of youthful female friendship. The author skillfully tells the reader quite a lot with only a few words--critical for achieving the story's depth, given its short length. And she does an equally good job of ratcheting up the tension leading up to the high-stakes climax. My only disappointment, really, was that I was left wanting to see/know/experience a little more about some of the characters.
I'm typically more of a novel reader, but some short stories, maybe because they are short enough that some things are inevitably left unsaid, can really capture the imagination in the best possible way. I'd put FRITO LAY in that camp.
