The Dark Is Rising
Middle grade · ages 9–14 · 820L · 2002
A genuinely eerie, atmospheric fantasy that respects its readers' intelligence; the prose is demanding and the stakes feel real, making it the gateway to grown-up fantasy for many kids.

The Grey King
Middle grade · ages 10–14 · 770L
Atmospheric and genuinely unsettling — Cooper's prose demands attention, and the Grey King himself is among the most formidable antagonists in middle-grade fantasy; not for kids who need cheerful escapes.
