The Most by Jessica Anthony

From “one of our most thrilling and singular innovators on the page” (Laura Van Den Berg), a tightly wound, consuming tale about a 1950s American housewife who goes for a swim in her apartment complex’s swimming pool one morning…and won’t come out.
 
It’s November 3, 1957. As Sputnik 2 launches into space, carrying Laika, the doomed Soviet dog, a couple begin their day. Virgil Beckett, an insurance salesman, isn’t particularly happy in his job but he fulfills the role. Kathleen Beckett, once a promising tennis champion with a key shot up her sleeve, is now a mother and homemaker. On this unseasonably warm Sunday, Kathleen decides not to join her family at church. Instead, she unearths her old, red bathing suit and descends into the deserted swimming pool of their apartment complex in Newark, Delaware. And then she won’t come out.

A riveting, single-sitting read set over the course of eight hours, The Most masterly breaches the shimmering surface of a seemingly idyllic mid-century marriage, immersing us in the unspoken truth beneath.
