Djinn Patrol on the Purple Line by Deepra Anapara

Jai lives in a shanty town in India. When one of his classmates goes missing he convinces his two friends, Faiz and Pari to join him in his search. What starts as a game soon becomes more sinister as other children begin to disappear from their neighbourhood. Rumours begin to circulate that the Djinn (or soul-snatching spirits) are the culprits. Anapara writes with humour and compassion about some real events that occurred in metrapolitan India.
