Each door at The Plex is painted a different colour. As Rafi Paterson soon realises, this is no ordinary suburban complex. Residents are urged to meditate, body corporate meetings take place in a dark warehouse, and the martial arts trainer from the end cottage offers to attack her to improve her self-defence skills.

Then the godsisters arrive for a two-week reunion in Cape Town: Elvi, the impeccable younger sister, and Bruna, the glamorous Italian who once lived with the Paterson family as an exchange student. When an art academic disappears after a party at The Plex, the godsisters turn to the sex diary found under Rafi’s bed for answers.

If you had the ability to avert a global disaster, would you step in — even if it meant never finding your way back?
