Seventeen year old Ree McKenna has three goals: get through high school, convince her crush she is more than his best friend's little sister, and save money for college. Fate, though, has other plans for her. After the untimely death of her older brother, Ree is haunted by dreadful nightmares and terrifying visions. To make matters worse, Ree has started to suspect that something dangerous is stalking her from the shadows. A night full of frightening surprises leaves Ree with unsettling news.

After all, Ree is the only mortal standing between the Earth and utter darkness. Set in Savannah, Ga, Mortal Obligation is the first book of The Dark Betrayal Trilogy.
