Shout-Out: The Dark Intercept by Julia Kelier

When the state controls your emotions, how hard will you fight to feel free?

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.

Much like the device itself, The Dark Intercept will get under your skin.
