Half-human, half-angel, Meridian Sozu has a dark responsibility. Sixteen-year-old Meridian has been surrounded by death ever since she can remember. As a child, insects, mice, and salamanders would burrow into her bedclothes and die. At her elementary school, she was blamed for a classmates tragic accident. And on her 16th birthday, a car crashes in front of her family home and Meridian's body explodes in pain.
Before she can fully recover, Meridian is told that she's a danger to her family and hustled off to her great-aunts house in Revelation, Colorado. It's there that she learns that she is a Fenestra - the half-angel, half-human link between the living and the dead. But Meridian and her sworn protector and love, Tens, face great danger from the Aternocti, a band of dark forces who capture vulnerable souls on the brink of death and cause chaos.
