Mount Fitz Roy

The survivors of the Earthcore disaster didn't learn their lesson. Now they're heading south—deep into the Andes, chasing a platinum deposit worth a trillion dollars and haunted by everything they left behind in Utah. Mount Fitz Roy drops readers into a world where greed, trauma, and something far worse than corporate ambition collide beneath some of the most unforgiving terrain on Earth. The stakes are financial, personal, and existential all at once, and Sigler makes sure you feel the weight of every bad decision these characters are about to make.

What distinguishes this book is Sigler's ability to sustain dread while keeping the pages turning at a punishing pace. His prose is precise where it needs to be and visceral when it counts, and he builds ensemble casts with enough distinct texture that the tension between characters feels just as dangerous as whatever is waiting underground. Readers who followed the first book will find the continuity genuinely rewarding; newcomers will get their footing fast. Either way, this is genre fiction that takes its own rules seriously.
