Legend (#1 of the Legend Trilogy) / Marie Lu
What was once the western United States is now home to the Republic, a nation perpetually at war with its neighbors. Born into an elite family in one of the Republic's wealthiest districts, fifteen-year-old June is a prodigy being groomed for success in the Republic's highest military circles. Born into the slums, fifteen-year-old Day is the country's most wanted criminal. But his motives may not be as malicious as they seem.
