Today is Mattias Madsen’s forty-second birthday. Again.

Mattias is not just a man with a photographic memory. He can travel to any moment of his life. But this ability has come with a hitch, as he’s become stuck in a loop. The same lakeside path. The same walk with his long-deceased sister. Something is off, though—these are not his memories at all. Trapped in a maddening limbo, Mattias is getting desperate. Reality is starting to fracture. Time itself seems to be ripping apart. And the dream of ever reuniting with his wife and daughter is fading fast.

Mattias’s only hope is Andrice, a fellow traveler on a mysterious mission of her own who offers Mattias escape. But breaking free comes with risks greater than Mattias can fathom. Someone is playing with his life and memories. As he navigates a paranoid new existence, his sense of identity threatens to fracture, and his memories of the people he loves recede further through time. Mattias could be heading toward a new reality—or oblivion.
