Seventeen-year-old Maddy Jacobsen has lived her whole life slipping out of consciousness. Diagnosed with narcolepsy, she experiences vivid dreams of another world—one filled with magic woven into technology, governed by physics as much as spells. In those dreams, she is older, brilliant, and known as the Physicist. She never imagines the dreams might be real—until, on her eighteenth birthday, she doesn't wake up. Maddy finds herself in Cerrigar, a world powered entirely by magic stolen from other universes, replacing the very woman she's been dreaming of: Madeleine Reiner, the Physicist who vanished while trying to stop the theft. As Cerrigar's magic begins to fail and the ruling Council demands increasingly dangerous solutions, Maddy is forced to step into a role she was never meant to inherit. With the help of allies—and haunted by the cost of obedience—she uncovers a truth that threatens not just one world, but many. Blending science fiction and fantasy, The Physicist is a story about consent, responsibility, and what it means to stay when leaving would be easier. The Physicist explores the ethics of survival at scale—and the courage it takes to choose care over control when the universe itself is watching.
