Empathetic Psychosis

Personality Disorder (Not Otherwise Specified)

My patients called me Dr. Holloway. My friends called me Jason. I won’t tell you what my three ex-wives called me but I’m sure you can guess. I was a psychiatrist (and a damn good one seventy percent of the time).

My adult life had been full of restarts, reinventions, and rehabilitations. This new beginning, though . . . this was supposed to be different. I’d taken a job at Margins Treatment Center in sunny Los Angeles as the Clinical Director.

Time Management

On the morning Gwen woke with the ability to manipulate time, it was already too late. She didn’t immediately realize she could stretch or compress time—that would come later. At first, all she knew was Dianne was gone, and she wasn’t coming back.

The Knacker Man

A year of living in the ground had not accustomed Moyer to the smell. He wondered how the French, who’d been at this business so much longer, could stand it. But if the officers who had trained his unit in the intricacies of trench life were any indication, they were so weary and battered as to scarcely notice the world around them any longer.

The Star Where We Meet

The most surprising thing about my journey (well, the first most surprising thing) is that the dream I experienced while traveling lasted a thousand years, a single dream stretching all the way to the Iota star in the Gemini constellation. I dreamt of Bindi, my childhood dog, a heeler and pointer mix who used to follow me everywhere; now it seems, she’s even followed me to this distant star.

The Stars Look Away From This Vessel

Draw a rectangular shape. Put a cylinder around it. Add a few small rectangles to any lines, such that they straddle them. At least one on the rectangle, and another on the cylinder. These are airlocks. The engine should look like a lighter stacked on top of a pack of cigarettes; don’t take too long drawing it, but make sure you color it in red, and then draw over it with a black marker.

Sarah’s Laugh

Everyone knows the Walls around the cities fell. What some people don’t remember is that the first one fell because of a laugh. It sounded like a ringing bell. Not like it came out of a baby at all. That was the first thing I told the scholar boy. He was a grown man, a researcher. He looked it, too. Big round glasses, chubby cheeks, curly hair.

The Aerialist

The typewriter proved, at first glance, to be a poor investment for a daring aerial escape. Kallista had been drawn to the typewriter from the moment she viewed it languishing in a Museum of Curioddities, a pun that 3% of Pennon City’s citizens might appreciate, if one rounded to the nearest human. The jury was out as to whether the placard’s sententious overview of Strange Olde Anti-Fae Percussive Instruments was someone’s idea of trolling or, equally likely, an exercise in mellifluous snake oil.

Ten Unsent Letters to the Dark Lord

1. I’m sorry, my lord.

2. I miss the sound of your voice, deep enough to shake the mountain fortress’s stones. I miss feeling it rumble in the soles of my feet. I miss the glow of your eyes while you paced the Chamber of Mysteries, lava burning in the pools below and the pointed arc of your throne at your back.

The Last Season of Your Life

On a wooded hillside outside Pittsburgh, where the rivers braid together and the bridges flash yellow in the sun, there stands an old private school no one ever remembers enrolling in. Ivy grips its cracked bricks. Moss blurs the leaded windows. To almost anyone looking, it appears abandoned. Unless they are the newly dead. If that is the case, it is more of an inevitability.
