The Bookshop of the Broken Hearted by Robert Hillman

Tom Hope doesn’t think he’s much of a farmer, but he’s doing his best. He can’t have been much of a husband to Trudy, either, judging by her sudden departure. It’s only when she returns, pregnant to someone else, that he discovers his surprising talent as a father. So when Trudy finds Jesus and takes little Peter away with her to join the holy rollers, Tom’s heart breaks all over again.

Enter Hannah Babel, quixotic smalltown the second Jew—and the most vivid person—Tom has ever met. He dares to believe they could make each other happy. But it is 1968: twenty-four years since Hannah and her own little boy arrived at Auschwitz. Tom Hope is taking on a batttle with heartbreak he can barely even begin to imagine.
