Iris thought she could ignore the shadows...until they came after everyone she loved. Seventeen-year- old Iris Kohl has been able to see both dark and light figures ever since a tragic incident three years ago. The problem is, no one else seems to see them, and even worse...the dark figures terrorize humans, but Iris is powerless to stop them. Although she's learned to deal with watching shadows harass everyone around her, Iris is soon forced to question everything she thinks she knows about her world and herself. Her sanity, strength, and will power are tested to the limits by not only the shadows, but also a handsome new teacher whose presence scares away shadows, a new friend with an awe-inspiriting aura, and a mysterious, alluring new student whom Iris has a hard time resisting despite already having a boyfriend. As the shadows invade and terrorize her own life and family, Iris must ultimately accept the guidance of an angel to revisit the most horrific event of her life and become the hero she was meant to be.
