Infinite Inconvenience - Terminally immortal, #1

Desperate to escape boredom and mandated moods, Jace a hedonistic nihilist immortal, flees to The Tesseract. An interdimensional slum where buildings phase in and out of history. There, he teams up with Kassia, a genius engineer who shares Jace's penchant for transactional nihilism. And she has acquired a new toy: Accelerated Enhancement Device(AED). Stolen from a corporate vault, the AED is supposed to be a luxury tool for aging scotch. But under the hood, it utilizes a tech that shouldn't exist on Earth. When Kassia overclocks it, the device doesn't just manipulate thermodynamics; it shreds local reality and time itself.When the AED triggers a massive Tachyonic emission, the air tears open. It is a door. Stepping through the breach is a woman covered in the dirt and soot from the past. Jace's past. But she didn't come alone. Following her through the rift are the beings that cursed Jace with immortality: ten-dimensional vibrating shadows— The Operators. And for the first time in centuries, Jace has a reason to be excited. Break out the good bourbon. The universe just decided to stop being boring.
