As a Christian humorist, Mary Eberstadt is the rightful heir and assignee of C.S. Lewis, and her heroine in The Loser Letters is the legitimate child (or perhaps grandchild) of "the patient" in The Screwtape Letters.

– P.J. O'Rourke, Author of Parliament of Whores

This is a wise, funny, and winning book.

– Michael Novak, Author of No One Sees God

Mary Eberstadt is one smart cookie. If you don't believe me, ask Satan.

– George Weigel, Author of The Cube and the Cathedral

This book is a gem. Through letters of advice from A.F. Christian, an enthusiastic convert to the cause of the new atheists, Mary Eberstadt deftly exposes the flaws in their views. Using the lingo of pop culture to hilarious effect, she offers a scathing satire of their question-begging arguments and shows with great wit that they are not just wrongheaded but downright laughable. Yet this spirited defense of Christian faith is also a poignant commentary on what it means to be human.

– Fr. Peter Ryan, SJ, Professor of Moral Theology, Mt. St. Mary's Seminary

Her letters raise questions outside religion, which engage readers. Where is A. F. Christian? Who encouraged her to write her letters? What traumatized her? Why?

The answers are revealed as the book progresses, revealing a mystery within a mystery that keeps you reading. . . . engaging, thought-provoking and amusing.

– Mark Ladas, Galveston Daily News, "Mystery within mystery about atheism, Christianity"

I think Lewis now has a rival . . . . This is good satire, uplifting and insightful and edgy and fun.

– Scot McKnight, Karl A. Olsson Professor in Religious Studies at North Park University, blogging at Jesus Creed, "Loser Letters 1"

I just read The Loser Letters by Mary Eberstadt and I cannot recommend it highly enough. For too long Christians have been a punch line for militant secularists. It's time somebody punched back. And Mary Eberstadt's new book The Loser Letters is an unexpected roundhouse to the new atheist movement. I urge you to pick it up.

– Matthew Archbold, of Creative Minority Report and the National Catholic Register; see his review "The Loser Letters vs. Big Atheism"

I didn't just think The Loser Letters was good; I thought it was remarkable. It's the best religious fiction I've read in a long, long time! If you're Catholic (or a non-Catholic Christian), you'll appreciate the way Mary Eberstadt works through the logic of faith and proves it's possible to believe in God without being a raving lunatic.
