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 classmate's tragic accident. And on her sixteenth 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-aunt's 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.
