Biting the moon - Martha Grimes

She didn't know who she was, where she was from or how she got there. She only knows that she is in a Santa Fe bed and breakfast alone. She is told by the owner that her father carried her in and she was asleep.

Daddy - she immediately knows that the man is not her father. She takes his jacket, money and the gun he has concealed in the trunk of his car and heads for the mountains, sensing safety in their forbidding presence. Months later, she walks down from the mountains, into Santa Fe, and into the life of fourteen-year-old Mary Dark Hope. They begin to realise the only way she will be free is to find the man who abducted her. In a succession of fast-moving episodes they move towards the inevitable and harrowing confrontation.
