Outlast. Outgrow. Outlive. In the ashes of Earth, evolution is the ultimate weapon.The Earth will never be the same. Ravaged by climate destruction, nuclear devastation, and other cataclysmic events, the planet and its people continue to undergo radical changes to survive. A portion of humanity now lives aboard the city-size utopian space station Astrea-the lucky few. Most who fend for themselves on the Earth's surface have become Nomads: plant/fungus hybrids connected to the growing planetary mind of Earth. The few remaining human societies on Earth survive through incredible cunning, calculation, and courage.

Shira and Myriam, cybernetically enhanced warriors hailing from the now destroyed Matriarchy of Wintersvilla, travel across the world in search of a way to protect two human-like girls with seemingly impossible powers. As the women clash with giant mutated beasts and a diverse array of deadly flora, they are intercepted by a Huntress and Hunter-catastrophically lethal creations of the old world thought to have gone extinct over a decade earlier. While these characters' paths intersect in surprising and explosive ways, ancient powers lurk in the shadows, wielding god-like influence over their lives. Will Shira and Myriam be able to overcome their nightmarish adversaries, or will they succumb to the endless perils of the neoevolved Earth?

"Mendel's Ladder is perhaps one of the most creative if not the absolute most creative work of fiction I have ever read. Fein's prose is solid. His characters are compelling. However, where Fein really shines is in wild, wild, WILD worldbuilding, lore, philosophy, and redefining genres. A part of me started reading book 2 just to see if Fein would ever let us down. Spoiler: he doesn't. He is a master of his craft and I can't wait to see where this series goes and what new bizarre and tantalizing ideas Fein will serve us next!" - NetGalley Review

"This novel is a lot in all the best of ways. It's rare to read something that feels simultaneously so ambitious and so well-realized. Nearly every aspect of Mendel's Ladder is a triumph: the pacing is lightning-quick and binge-readable; the writing itself is sophisticated, haunting, and utterly compelling; the characters are interesting; there's philosophical meat on these half-fungal bones. The world Fein has created has all the harrowing emptiness that made me fall in love with the 'Dark Souls' franchise; the pages practically ooze with implied lore, storied history, and audacious, fascinating detail." - Amazon Review

"Given the lethality, speed, and unimaginable destruction wrought by some of the characters in Mendel's Ladder, it was initially difficult imagining how an actual fight would play out. However, the battle scenes were incredibly detailed, and Fein truly gives you a perspective of the high-speed and primal carnage." - Steven Chisholm, Author of Bleeding Iris

"From the nightmarish terrestrial expanse to the seemingly serene domain of Astrea, every detail feels meticulously crafted with a fevered imagination and methodical construction." - Bookbub Review

"From the outset, Mendel's Ladder stands out for the sheer uniqueness of its world-building. The dystopian Earth of the future is unlike anything I have ever encountered." - Goodreads Review

"Seriously. This is awesome. Go for it!" - Daniel Georgiev, Author of Mathsmagica

"Strange and beautiful." - Marie Montine, Author of Arising Son
