Hemingway and the Catholic Question

I've written about Hemingway a few times before (see here [on 47 endings], here [on his Catholicism], here [in relation to Cormac McCarthy], here [on writing], here [on Farewell to Arms], and here [on Pilgrimage]) so I'm delighted to have been told in the combox about a new book on Hemingway's Catholicism.

The really good news is that it's affordable (especially the Kindle version) and comes highly recommended by H. R. Stoneback, doyen of Hemingway scholars.
