Nine
(Book)

"Lucy doesn't remember anything, even whether or not she likes milkshakes. All she remembers is that Olivia told her to run. When she encounters Zoe, a waitress at a small town diner, who has her own hidden past, Lucy instinctively trusts her. Powerful people are after Lucy, though, and as the girls continue to flee from the unknown, it seems Lucy may not be an innocent child. Her skills are more fitting for a hardened military veteran than a young girl and, as she begins to remember her origins, it turns out she may be more weapon than human." -- Library Journal.
