Since this is a sale celebrating trans authors, I'll include a tiny bit about myself. I am a disabled nonbinary author working around the clock to bring this fiction to life. I'll keep doing this for as long as I am able. Which is to say no one can stop me, not even myself haha.
It's always my goal for my work to explore the intricacies of survival. The world is so beautiful, and so ugly. Often at the same time.
About:
Some time ago, a glimmer broke the horizon, blistering the periphery of sight and mind. Since then it has evolved to claim a name. The Beyond. A vast, ravenous entity gaining purchase in the world with each passing day.
Amidst the chaos, Nieve Lyonne rises to fill the long-vacant position of Biotheologist. Caught in a clash between the demands of her superiors, a terrified society, and her vibrant curiosity for the entity knocking on their door, Nieve must find a balance between holding on to humanity and letting the world bend her into a shape of its own.
Beyond Bringers is a sci-fi horror novel about limits, language, and where humanity is lost.
