Practical and hard-headed John Grimes is not the sort to believe in ghosts but he's willing to give psychics a chance when shapely Sonya Verrill, a commander in the Federation Survey Service, proposes a ghost-hunting expedition in the sector around Kinsolving's Planet. Out where the fabric of space wears thin, ships have encountered Rim Ghosts—apparitions of craft and crewmates from alternate universes. When Grimes organizes a séance to make contact, their ship is yanked into an alternate universe, and their only hope of getting home lies in a lost relic - a sleeper ship from the first age of space exploration.
