I can see some forbidden loves in this book. The love between Velutha and Ammu was quite shocking because Velutha is untouchable. Also, the love between Rahel and Estha was shocking too. I felt Ammu will be in love with someone, but I never imagined and thought about Rahel and Estha having sex. I think Roy tried to emphasize the power of love by forbidden love or was just a big fan of love.
