Siddharth Singh compiles in Bengali a collection of fairy tales sourced from both Indian and international traditions. His work দেশ-বিদেশের রূপকথা (Desa Bidesera Rupakatha), published by Patit Paban Book Stall, Kolkata, gathers stories in the rupkatha tradition — imaginative narratives that have long been part of Bengali storytelling for children.
