What Book Should I Give a Strong Pantheist?

Questions about suggestions for a book to give a strong pantheist who’s a fan of Neale Donald Walsch, and how karma is different from the parable of the sower in Matthew 13 or the teaching about reaping what you sow in Galatians 6.   My neighbor, who is a strong pantheist, gave me Conversations with God by Neale Donald Walsch. Do you have any suggestions for what I could give him in return? How is karma different from the parable of the sower in Matthew 13 or the teaching about reaping what you sow in Galatians 6?
