“Mohan applies meaningful nuance to the sequences that might seem like they just want to get our blood pumping, aware that people reveal their truest selves in details like the positions they choose, their body language, what pushes them over the brink of orgasm. Here, sex is not a writer’s device but a real thing shared between characters that behave like real people. Better still, he’s not timid about pleasure for its own sake. He wants us to watch, at our own peril. Four stars.”
