Celestial Entanglement

Two years after losing her twin sister in a car accident, PhD candidate Sage Winters arrives at a prestigious mountain observatory symposium only to be assigned—by administrative error—to the same tiny studio as Kieran Blake, the confident rival she’s sparred with for two years.

When Kieran reveals he’s been haunted by memories of Luna that he could not possibly know, the two realize a stellar quantum event at the moment of Luna’s death entangled their consciousness, letting them share thoughts, memories, and even heartbeats through touch.

As they map anomalous gravitational data that seems tied to their bond, the connection intensifies past safe limits and forces an impossible choice about how far each will go to protect the other.

The book braids their scientific collaboration with Sage’s grief work and the slow dismantling of the misunderstandings that kept them apart.

Tropes: academic rivals to lovers, forced proximity / one room, fated mates / soulmate bond, psychic or telepathic connection, grief and healing, hidden depths (secretly working-class hero), class difference, self-sacrifice, touch-triggered connection, twin loss (what these mean)
