Hollow-Boned Universe

On an alternate Earth lies the country of Tar, a small continent occupied by humans and winged people known as hollow-boned. The government controls many aspects of its citizen's lives, including the media they consume and where they can and cannot travel. Magic powers crop up randomly in many families and those that show potential are often recruited by the Sentinels of Light, a private organization that fights crime and maintains peace in the cities. But all is not as the government would like its citizens to believe. There are secrets that, if exposed, could shatter the fragile peace that holds this country together.
