Seventeen-year-old Steffie Rogers is not happy. Her mother, Barbie, has been suffering from love lunacy since before Steffie was even born. What is love lunacy? It’s what happens to her mom when she has affairs with married men. The first stage is the Secret Smile and the last stage occurs when the relationship falls apart: Barbie picks another town in Maryland and they move, which they’ve done 14 times.
Now Steffie lives on Jones Island and is working as a maid at a country club over the summer (long story). She’s in love with handsome lifeguard Keith McKnight, but he already has a girlfriend. When Keith offers to teach Steffie how to swim, she finds herself in his arms and fighting the symptoms of love lunacy. But with the help of her feisty, older friend Alice, she’s determined not to drown in her mother’s problems.
Still, Steffie is about to discover that swimming against the current isn’t so easy.
