Please be aware that this discussion guide will contain spoilers!

  1. The Foursome is told through Sarah's perspective. How does seeing events through her eyes shape your understanding of the other central characters, her sister Adelaide, her husband Eng, and his brother Chang? Were there moments when you felt the limits of Sarah's point of view, or times when what she couldn't or wouldn't see told you more than what she observed directly?
  2. The novel explores the idea of complicity — the ways people participate in systems of harm through silence, willful ignorance, or simply the ordinary routines of daily life. Which moments in the novel struck you as the most powerful depictions of complicity, and how does Kline dramatize something as invisible as choosing not to see?
  3. The title The Foursome frames these four people as a unit, yet the bonds between them are hardly equal. How do the different pairings within The Foursome — the twins, the sisters, the two marriages — pull against each other? Which relationship did you find most compelling, and why?
