Generally speaking, it’s a good idea to take Kathryn Schulz’s book recommendations. However when she refers to something – in this case J.M. Ledgard’s Submergence – as “the best novel I’ve read so far this year,” you really ought to listen up. By the time she invokes Philip Gourevitch, Anne Carson, W. G. Sebald, and John Le Carré in her review of that book, you ought to be reaching for your wallet.
