Caraval

Why these tropes fit

Caraval weaves together an arranged-marriage setup, a legendary competitive tournament, and a desperate sister-rescue quest, all filtered through an unreliable narrator who cannot confirm where the performance ends and reality begins. Magic saturates the game, and the heroine must outpace rivals across five nights to prevent her sister's permanent disappearance.
