The Children of Darkness is book one in the Seekers dystopian trilogy
"But what are we without dreams?"
A thousand years ago the Darkness came--a time of violence and social collapse when technology ran rampant. But the vicars of the Temple of Light brought peace, ushering in an era of blessed simplicity. For ten centuries they kept the madness at bay with "temple magic," eliminating the rush of progress that nearly caused the destruction of everything.
Orah and Nathaniel, have grew up in a tiny village, longing for more from life but unwilling to challenge the status quo. When Orah is summoned for a "teaching"—the brutal coming-of-age ritual that binds the young to the Light—Nathaniel follows in a foolhardy attempt to save her.
In the prisons of Temple City, they discover a secret that launches them on a journey to find the forbidden keep, where a truth from the past might unleash the potential of their people, but may also cost them their lives.
