Legend Trilogy By Marie Lu

The only reason I'm adding this is because it's the best book series I've ever read. I loved the plot/characters, and even though it's not romance themed, the author nailed it. I read the series two years ago, and yet it still resonates within me. I'll link where you can read for free at(You'll need an epub and pdf reader).

Summary:

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.

From very different worlds, June and Day have no reason to cross paths—until the day June's brother, Metias, is murdered and Day becomes the prime suspect. Caught in the ultimate game of cat and mouse, Day is in a race for his family's survival, while June seeks to avenge Metias's death. But in a shocking turn of events, the two uncover the truth of what has really brought them together, and the sinister lengths their country will go to keep its secrets.
