About this ebook
Sarah Kessler, pulled back from private life into the center of a crisis with her name already on it, has to build a task force out of engineers, ethicists, and a systems architect still carrying the weight of the mistake that started all of this. As pressure nodes fail across the globe and the world's governments demand answers faster than the evidence can honestly provide them, the team that will define the next three books of this series first has to survive deciding, together, what a planet-scale emergency actually asks of the people responsible for it.
COLLAPSE is where THE DEEP VEIN becomes an ensemble series — and where the coalition built in Geneva finally gets tested by the crisis it was built for.

About the author
Andi Anriansyah is a senior geoscience professional with more than 17 years of experience in the oil and gas, mining, and infrastructure industries. He earned his Bachelor's degree in Geological Engineering from the Bandung Institute of Technology (Institut Teknologi Bandung) and has spent his career working on subsurface evaluation, resource development, and geological risk assessment across a wide range of complex projects.
His professional experience includes oil and gas developments in Sumatra and Papua, geological studies for the Batang Toru Hydroelectric Power Project, and international petroleum asset evaluations in Madagascar. Throughout his career, he has worked at the intersection of geology, engineering, and decision-making, where critical choices must often be made despite incomplete data and where the consequences of those decisions can extend far beyond what is immediately visible.
That reality forms the foundation of COLLAPSE.
The novel draws inspiration from years spent interpreting geological uncertainty, assessing hidden risks deep beneath the Earth's surface, and asking a question that gradually evolved from technical curiosity into fiction:
What if the subsurface systems we study possess a level of interconnected behavior far beyond anything modern science has yet recognized?
Rather than using geology merely as a backdrop, COLLAPSE places scientific reasoning, engineering judgment, and the ethics of decision-making at the center of its story. Its characters face the same dilemma encountered daily by engineers, geoscientists, and policymakers: whether to act before certainty exists—or risk acting too late.
Through The Deep Vein series, Andi seeks to bridge two worlds that rarely meet: the analytical discipline of Earth science and the imagination of speculative fiction. The result is a series grounded in technical realism while exploring one timeless question: how little humanity may truly understand about the planet beneath its feet.
