Numbers is a book that’s hard to categorize. It starts out as urban fantasy, then becomes more of an adventure novel, then seems to be a “teaching life lessons” story toward the end.
The heroine, Jem, has a supernatural “gift” that has caused her no end of grief. She sees numbers when she looks at people. As a little girl, she didn’t know what the numbers meant — not until her mother’s number turned out to be the day she overdosed on drugs.
