The Great Christ Comet
I'll admit that I am quick to promote this book purely because of how gorgeous the cover is, and how nicely it's all put together. It's a hardcover in a nice dark teal colour, with lovely full-colour photos throughout. In the words of Eric Metaxas (New York Times best-selling author, Bonhoeffer):
"I am simply in awe of this book. An absolutely astonishing triumph."
