Sisterhood is difficult for Su and Emerald. Su leads a sheltered, moneyed life as the picture-perfect wife of a conservative politician in Singapore. Emerald is a nihilistic sugar baby in New York, living from whim to whim and using her charms to make ends meet. But they share a secret: once, they were snakes, basking under a full moon in Tang dynasty China. A thousand years later, their mysterious history is the only thing still binding them together. When Emerald experiences a violent encounter in Central Park and Su boards the next flight to New York, the two reach a tenuous reconciliation for the first time in decades. Su convinces Emerald to move to Singapore so she can keep an eye on her--but she soon begins to worry that Emerald's irrepressible behavior will out them both, in a sparkling, affluent city where everything runs like clockwork and any deviation from the norm is automatically suspect. Razor-sharp, hilarious, and raw in emotion, Sister Snake explores chosen family, queerness, passing, and the struggle against conformity. Reimagining the Chinese folktale "The Legend of the White Snake," this is a novel about being seen for who you are--and, ultimately, how to live free.
