Maddie has been able to see numbers on peoples' foreheads since she can remember, but until her father was killed in a police shootout, it didn't click to her or anyone else what those numbers meant. She's able to see the date people die, but she can't seem to do anything to change the outcome. Several years later, her devastated mom is an alcoholic, and has Maddie do "readings" for paying clients. She predicts the death of a client's son, and when that actually happens, the client calls the police. This leads Maddie on a nail-biting hunt for the killer.
I loved how when a new character was introduced, the author would put the death date in parenthesis after their name. It was interesting to think about what it would be like to have a skill/talent/curse like this.
