The dark intercept

"In a radiant world of endless summer, the Intercept keeps the peace. Violet Crowley, the sixteen-year-old daughter of New Earth's Founding Father, has spent her life in comfort and safety. Her days are easy thanks to the Intercept, a crime-prevention device that monitors emotion. But when her long-time crush, Danny Mayhew, gets into a dangerous altercation on Old Earth, Violet launches a secret investigation to find out what he's hiding. An investigation that will lead her to question everything she's ever known about Danny, her father, and the power of the Intercept"--OCLC.
