The Black Prism (2010) is the first book in Brent Weeks’ Lightbringer series, a high-stakes fantasy saga set in a world where magic—called drafting—is derived from light and color. The story follows Gavin Guile, the Prism, a near-divine figure who can harness all colors of light and is tasked with maintaining political and magical balance in the Seven Satrapies. But Gavin harbors a dark secret: he’s actually Kip, his presumed-dead brother, living under a stolen identity. When Kip, a teenage peasant with latent drafting abilities, enters his life, Gavin must confront his past while navigating war, religious fanaticism, and his own fraying sanity.
Weeks’ magic system is meticulously crafted—each color of light grants unique powers (e.g., blue brings logic, red fuels rage) but drains the drafter’s lifespan. The novel blends political intrigue, familial drama, and explosive battles, with morally gray characters who defy easy hero/villain labels.
