So Yesterday (2009) Parents Guide: Is the book OK for kids?

This novel contains no sexual content beyond mild, nervous flirtation between the main characters. Hunter has an obvious crush on Jen, which begins when he notices her unique shoelaces in Chapter 3, and their dynamic remains rooted in banter and shared curiosity.

The story avoids the typical 'party scene' tropes common in Young Adult fiction, keeping the tone clean and accessible for…

The core of the book is a sharp critique of consumer culture and the manipulation of teenage desire. Hunter works at the second tier of a 'cool pyramid,' where he is paid to identify trends so corporations can mass-produce them for profit. Through scenes like the focus group in Chapter 6, Westerfeld deconstructs the psychological tactics used in advertising and product engineering. The antagonist group, the Jammers, present a radical anti-consumerist philosophy, viewing brand sabotage as a form of social justice…
