Crisp and Clear
Sure, the narrator has her rambling and reflective, but for the most part, the writing style is quite civilized, Austen-esque, even. The writing style is crisp and clear and tells the readers what we need to know in a detailed way without getting too derailed or at all confusing. For example, here is how the Loyal Order of the Basset Hounds is described:
The Loyal Order of the Basset Hound had been conceived as a society for the elect among Alabaster students—"elect" meaning those from particularly loyal and moneyed Alabaster families, and meaning also those who were considered cool enough. (21.16)
Instead of just mentioning the Loyal Order in passing or leaving the reader in suspense to wonder what exactly being an "elect" student means, the book tells us in no uncertain terms. Like we said—crisp, clear and to the point.
