The Alaster Trilogy

In a future where the surface of the earth is uninhabitable, humanity is forced to survive in an underwater facility. But this is not the sanctuary humanity had hoped for. A. H. Ostmo crafts narratives that are as gritty as they are beautiful. Discover the author’s unique vision and immerse yourself in stories that challenge the boundaries of reality.

What is Gia up against?
Monsters outside.
Accidents inside.
The Trellis Facility can’t be the way humans were meant to live.
With her father, Garridon Hamiltoni, as the Head of security, Gia was trained to keep the community safe. She knows that audio surveillance is difficult to understand when too many people speak at once, which is why the community members are discouraged from speaking in the corridors. She knows that certain words— like Alaster— trigger the artificial intelligence systems to listen closer to the conversation.

The suffocating control can’t withstand the weight of questions about what happened to the girl who disappeared. Searching for truth, Gia uncovers the mess of deception around the mythical submarine, called Alaster, which could provide a chance to leave the Trellis.

In the first book of the Alaster Trilogy, A. H. Ostmo shapes an underwater world that explores belief systems and challenges worldviews. With microbial-based systems and energy from hydrothermal vents, the Trellis facility is located in one of the most extreme environments in the universe. No sunlight, shadowy creatures, and more pressure than a human can withstand— what better setting to examine the internal conflicts of the human mind?
