Leo had never been afraid of numbers. Equations were puzzles, and puzzles had answers. But when his advanced algebra professor handed him a dog-eared copy of Polynomials by Barbeau, Leo felt a flicker of unease. The cover was unassuming—blue, white, and orange—but the problems inside were legendary.
