Douglas Wilson has written a response to Sam Harris’ atheist manifesto Letter to A Christian Nation.  Wilson’s book, Letter from a Christian Citizen, has some impressive accolades.

"Douglas Wilson has written a book that can give Christians a place to stand in regard to Sam Harris’ book Letter to a Christian Nation.
The primary usefulness of Wilson’s book is that it gives readers a
point-by-point response to the arguments advanced by Harris in an
engaging and compelling way."
