Threshold: Sometimes the boundary is only beginning

In a future that already looks too much like our own, a headset promises to cure loneliness by turning memory into a place you can walk back into. Put it on, and the people you've lost take your hand again. Diane uses it to see her husband. Marcus, to find the only version of his grandmother who still knows his name. Thousands of others, every night, just to feel a little less alone for an hour. No one knows those worlds aren't built from nothing. They're stitched together, one memory at a time, from a space shared among every user. And at the bottom of that shared space, never truly deleted, survives the anguish of a man who died years ago, a faceless presence beginning to surface in the lives of strangers who have never met. An engineer carrying a confession he's never made. A journalist who has already watched this story end badly once before. An executive who calls everyone "family" and never looks the people he fires in the eye. And four people about to discover, too late, that they share the exact same grief. Threshold is a novel about loneliness, technology, and the price of being seen, even when there's no one left on the other side to see you.
