Two dead bodies. One murder weapon. No memory of either.
Marcy Mayhem has had bad shifts before, but waking up between two corpses on the Fresh Start Retirement Starship is a new personal low.
The ship is drifting toward an unknown region of the Oort Cloud, and the passengers are already seeing things they shouldn't. Ghosts in the halls, ship going off-course in the middle of nowhere and, because this is Marcy's life now, the cafe still needs running.
Her terrifyingly organized boss, David Brenner, wants order.
Marcy mostly wants not to be arrested.
But as the Fresh Start slips deeper into space madness, Marcy realizes the murders are only part of the problem. Someone is sabotaging the ship; someone is using the chaos to hide the truth, and the evidence keeps pointing straight at her.
Now Marcy has to solve a mystery of doubles, ghosts, learn about the Ship's dark and secret Lower Decks, stop the rebels from sabotaging the ship, while dealing with very picky retirees before the Fresh Start becomes a floating crime scene in the dark.
Because on this retirement starship, even murder comes with complaints.
