Is the Ending Happy or Sad?

Who Will Like This Ending
Readers who enjoy endings that are shocking and ironic will find a lot to talk about here. If you prefer every thread tied up neatly, it helps to know in advance how Pierre Boulle closes the story, which is exactly why many readers look it up. Either way, the final chapters reward a second look once you know where everything is heading, because small details from the middle of the book start to matter. If you are reading with a group, agree beforehand whether everyone has finished, so nobody has the last chapters spoiled.
