Breasts and Eggs
I think if I were to recommend this book to someone I would do it simply: do not read the second part. This is an amalgam of two novellas (explicitly demarcated as such in the final product), and the first book — rife with a crisper style and interesting voices — is dulled by the second, which feels more meandering and, well, less interesting.
So, ignoring the disjoint artifact of the combined book, what did I like about the first novella? It was fascinating: a specific and feminine perspective on maturity and artifice, centered in a kind of outsiderdom experienced by all three protagonists.
