Jin Cheng is the brilliant theoretical physicist at the center of 3 Body Problem — one of the 'Oxford Five', a group of gifted scientists whose lives are upended when they discover that an alien civilization is coming and that the laws of physics themselves seem to be unraveling. Sharp, idealistic, and increasingly burdened by the weight of what she learns, Jin becomes humanity's reluctant strategist against an existential threat centuries away.
Her arc moves from wonder to dread to resolve. As she unravels the mystery of the mind-bending VR game, the death of her mentor, and the truth of the San-Ti, Jin must reconcile her faith in science with a future that may already be lost, and decide what she is willing to sacrifice for a fight she may not live to see won.
