Book cover design by @JoelHolland_Studio for 'Only Love Can Break Your Heart' by @edtarkington. #OnlyLoveCanBreakYourHeart is technically a mystery novel, one in which the mystery comes late (with good reason; it's best explained in light of earlier events). But it's a "mystery" in the same sense that Margaret Atwood's novels are "science fiction". "If a book could have an Instagram filter, Tarkington's would be set on something called "Nostalgic."
