Privilege by Megan Wobus

A World Without Weapons

In 2034 the Peaceful Society of Greater Maryland is safer than it's ever been. Women have seized power, guns are outlawed, and aggression is carefully monitored.
Amity Bloome has spent her life trying to do everything her mother, teachers, and government expect of her. Now she is ready to take her Oath and start the rigorous training to become an Officer, but nothing on Oath Day goes as expected.
Amity is sent on a new mission far from home, and gets mixed up with a man leading a dangerous group determined to regain control.

Privilege is a young adult utopian/dystopian romance and the first book in the Peaceful Society trilogy.
