Constructing a Booklist

I'm building a book list of short but informative and interesting books to give away to my congregation. There are plenty of longer tomes, but I'd like something short and sharp without being superficial. In a way this list represents my worldview because I only want to recommend books I'm confident in and I feel represent my worldview.

These are the topics I have books for so far ...

• Abortion: Abortion and the Early Church by Michael J. Gorman
• Apologetics: The Journey by Peter Kreeft
• Contentment: The Rare Jewel of Christian Contentment by Jeremiah Burroughs
• Discipleship (How-to): One to One Bible Reading by David Helm
• Discipleship (tough spurring-on): Am I Really a Christian? by Mike McKinley
• Ecology: Pollution and the Death of Man by Francis Schaeffer
• Gospel: Making the most of the Cross by John Chapman
• Genesis: Did Adam and Eve really exist? by John Collins
• Heretical groups: Defending the Faith by Richard Abanes
• Heaven and Hell: The Great Divorce by CS Lewis
• Idolatry: Counterfeit Gods by Tim Keller
• Jesus (history): Jesus: A very Short Introduction by Richard Bauckham
• Jesus (theology): From Glory to Golgotha by Donald Macleod
• Parenting: Loving the Little Years by Rachel Jankovic
• Pornography: Sexual Detox by Tim Challies

These are the topics I don't have books for ...

• Discipleship (gentle spurring-on)
• Doctrines of Grace
• Cosmology
• Homosexuality
• Gender
• Judgement
• Justification
• Sanctification
• Sin (A summary)

Books I've heard might be useful and may find their way onto the list ...

• Satan and Demons: Living with the underworld by Peter Bolt

Are there any topics I've missed, books I should find a topic for, books that I should replace or books that need to be added?
