Book
One
The world is unraveling. The myths remember. And the echoes are calling.
Across the globe, strange visions stir. Old stories shift in the shadows. And something forgotten begins to wake beneath the surface of the modern world.
Six teenagers, scattered across continents, find themselves drawn into a mystery they never asked for — and a danger far older than any of them understand.
Magic is returning. The seals are weakening. And the line between myth and memory is starting to blur.
The Hidden World was never gone.
It was only waiting.

Featured Review
“From the first chapter, it feels like a five star read.”
Natasha Corrado, Reedsy Discovery
An incredible YA fantasy that will have you glued to the page
and on the edge of your seat!
This book is exceptional. That must be said about Mohs’s debut novel. For an author to produce such a compelling story line and weave together such a strong plot structure for the first time, that is a feat only few can accomplish.
From the prologue the reader is thrown in the middle of a world torn between two realms. One is dark and magical, sinister even, and the other is ours. Perfectly normal, perfectly historical, nothing out of the ordinary. All it takes is a few ancient beings to start toying at the seams to bring out the magic in six teenagers who aren’t even aware of the power they hold. From the jump, the reader is immersed. From the first chapter, it feels like a five star read.
Seth Mohs’s prose sucks the reader in like no other. Each sentence is carefully articulated to visualize and imagine exactly what is written on the page. From the first introduction of each character the reader immediately likes them and enjoys following them around. The audience can feel what the characters are feeling due to the vivid and imaginative descriptions. Every page has action and adventure so unique to this story that it is a refresher of a novel. Echoes of the Lost World is reminiscent of the Percy Jackson series with its personable characters and intense monsters.
There is simply nothing about this book that isn’t top tier. The writing is exceptional, the plot structure is well done, each chapter has the perfect amount of character development and action, and the way the story line itself weaves together is fun and entertaining. It is an honor to read a book as great as this one, and since it is projected to be a seven part series, there is plenty to go around!
Echoes of the Lost World is a novel that YA readers will devour, even older readers as well. This was a truly fantastic book and readers everywhere will eagerly anticipate the next installments to come!
