The Bridge of San Luis Rey by Thornton Wilder

The Bridge of San Luis Rey, Wilder's second novel, tells the story of five people who plunge to death when the Incan rope bridge they are walking on collapses. Exploring the events that led them to be on the bridge at that moment inspires a philosophical examination of chance and inexplicable tragedy.

It was first published in 1927 to worldwide acclaim. The novel won the Pulitzer Prize in 1928, and was the best-selling work of fiction that year. Wikipedia
