A glittering, bold, darkly funny novel about two sisters—one in New York, one in Singapore—who are bound by an ancient secret. 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 as she freely uses her beauty and 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 an affluent city where everything runs like clockwork, but no deviation from the norm can be tolerated. Dark, hilarious, razor-sharp, and raw in emotion, Sister Snake explores chosen family, queerness, passing, and the struggle against conformity. Boldly 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.
