Book excerpt: Khadim has no idea why he's been called into the office of Dr. Danielson, the Vice Principal at Sheffield High. At first, Danielson is cagey, using a minor violation to keep the boy at school for detention. But as tension mounts, Danielson alternately plays good cop and bad, and winds up catching Khadim in a series of lies about crimes he may (or may not) have committed. The truth shifts constantly in this riveting cat-and-mouse thriller from Pulitzer Prize finalist Rajiv Joseph. What’s bothering Dr. Danielson? What are the secrets that trouble Khadim? As the semester reaches its final hour, the time for revelation begins. The North Pool is a psychological drama that weaves a timely character study about racial and cultural profiling in America, skillfully using an interrogation to peel away ever more unexpected layers of the characters’ lives as they navigate our increasingly complex society.
