What Book Would You Recommend to Witness to an Agnostic Friend?

article - Randy Alcorn
Question from a reader: I work with an agnostic. I've shared my faith with her in a very nonconfrontational way for two years now. She's very quick to shoosh me, so I witness more in the gift of mercy and hospitality and less in prophet! Do you have a recommendation for a book that I could give her? She loves history and has a very inquisitive mind. She asks me questions quite often about the Christian "religion." She always has an audio book going in her car and at her desk, so audio would be ideal.
