Twenty-one-year-old Kara has always suffered from anxiety, has never had a boyfriend and can’t seem to keep a job for longer than a few days. Kara’s life sucks and that’s the truth of it. Things may start looking up, though. She has a job she thinks she can keep and every day, she eats her lunch on the roof of the building in peace away from people.
One day while on the roof she witnesses a disturbing event taking place on the ground below her. Black smoke has appeared out of nowhere. People are screaming and dropping to the ground. Kara watches, frozen and terrified as the smoke makes its way through the city.
She must now decide whether to wait for help that may never come or take a chance and leave to face whatever it is that is attacking the city.
Her choice is made for her when Lincoln, an angel, appears and tells her she must join him and the other angels in a battle against fallen angels and other dark supernatural beings who have joined forces to destroy the Earth.
Kara must now overcome her fear and help save the world, but can she do so without falling in love with Lincoln?
