PositiveOpen Letters Review\"Enveloped in a mind-bending fractal of Renaissance art, eschatology, and Germanic history, Lentz’s Schattenfroh teeters between brilliance and inscrutability. In his introduction to an English audience, German author and musician Michael Lentz showcases his erudition and presents readers with an intoxicating riddle to solve. Translated by Max Lawton, this surrealist work draws readers into a journey of metaphysical proportions, pushing the boundaries of linguistics and narrative ... Despite its panoptical narrative and clever constructs, its complexity comes at a cost. The narrative becomes constipated at times due to its endlessly referential and self-reflexive theatrics, including scrambled names, anagrams, and frequent interruptions that substitute mental gymnastics for clarity ... It’s a novel that demands patience, multidisciplinary comprehension, and an openness to grappling with Lentz’s experimental devices. Just as the end of the novel returns to its beginning, readers seeking to grasp its depths must reread it, peeling back each layer with every pass. It could very well be a century-defining novel or remain cherished solely by a targeted niche willing to lose themselves in its shadows—only time will tell.\
