The Eyres have written over a dozen books, with several of them becoming bestsellers. These include Teaching Your Children Values, which was the first parenting book to make it to the position of #1 New York Times bestseller since Dr. Spock's book. Eyre's Spiritual Serendipity: Cultivating and Celebrating the Art of the Unexpected was published by Simon & Schuster in 1997. Other books by Eyre include The Discovery of Joy (1974), Teaching Children Joy (1986), The Birth We Call Death with Paul H. Dunn, Life Before Life (2000) and How to Talk to Your Children About Sex, written with Linda. Besides writing these non-fiction works, Eyre wrote a novel entitled The Awakening. A more recent book by the Eyres, Empty Nesting Parenting: Adjusting Your Stewardship as Your Children Leave Home, has been recommended as reading for parents of college students.
