Manil Suri grew up in a large crumbling apartment in Bombay (now Mumbai), which his parents, who were Hindu, shared with three Muslim families. At age 20, Suri broke free from their single room and came to the US, where he finally found the freedom to embrace his sexuality and find a life partner. But the room kept wrenching him back to Bombay. By now, real estate prices had risen so much that neighbors had begun conspiring to take over the room. Eventually it was only his mother, Prem, left, who had staked all her happiness on her son but was unable to escape the room’s hold on her. When a rash of mysterious incidents seemed to beset the room, Suri realized how little time he had left to convince Prem that a happier life might await beyond the four walls that both enthralled and imprisoned her.

As Mumbai empties under the threat of imminent nuclear annihilation, Sarita, a thirty-three-year-old statistician, can only think of one thing: being reunited with Karun, her physicist husband. Why has he vanished? Who is he running from? How will they form the family of three he's always wanted? To find him, Sarita must journey across the surreal landscape of a near-abandoned city, braving gangs of competing Hindu and Muslim hoodlums.
