OneWord Journal has been inviting pastors, missionaries and church leaders to list the ten books they would want to have should they ever be marooned on an island. From the looks of it, members of College Church's Christian Education board would have a field day exchanging books on that island. Here are the list from various board members.

Jon Eckert (board chair)
Here's my list based on a quick scan of the bookshelves in my office, with the addition of the 2017 World Almanac to give me access to plenty of thins to memorize.
ESV Study Bible
Systematic Theology by Wayne Grudem
Mere Christianity by C.S. Lewis
The Reason for God by Tim Keller
Harry Potter and the Goblet of Fire by J.K. Rowling
Letters from a Nut by Ted L. Nancy
Daring Greatly by Brene Brown
Thinking, Fast and Slow by Daniel Kahneman
Visible Learning and the Science of How We Learn by John Hattie and Gregory Yates
The World Almanac and Book of Facts 2017

Dan Haase
I cheated a bit by going with a few trilogies (glad the board members are fessing up).
The Message, Eugene Peterson, The Bible as a really good story
The Brothers Karamazov by Fyodor Dostoevsky, because it is a masterpiece and, therein, deserves many readings
Mortification of Sins by John Own, a deserted island (or life) affords one time to do some good soul work and this book is a classic that has stood the test of time. Here's a free download of the book.
The Art of Divine Contentment by Thomas Watson, the fostering of gratitude can allow one to make it through any experience. And here's a free download of this book.
A Diary of Private Prayer by John Baillie, on of the best prayer resources out there.
The Space Trilogy by C.S. Lewis, the last book is his best work in my opinion, but you need the first two to get there.
The Singer Trilogy by Calvin Miller, a fresh and poetic reading of the Gospels, Acts and Revelation
The Lord of the Rings Trilogy by J.R.R. Tolkien, a good epic to go there and back again.
A Treasury of Dr. Seuss, because whimsy matters
Haiku Anthology, nothing like haiku to help you live in the present tense and give thanks.

Mindy Rynbrandt
