Book Description
Pursued by a terrifying demon, a young knight flees across the radioactive ruins of a fairy-tale land. His only weapon is the same cursed power that once destroyed this world—what some would call magic, and others would call technology.

As his relentless enemy draws closer, the knight's terrible secrets begin to unfold. How many lives has he lived? Is this the past, the present, or the future? Is he destined to bring love, or unimaginable destruction? And if he fails…will humanity get another chance?

The English-language debut of Austrian-German graphic novelist Lukas Kummer arrives like a thunderbolt, arcing brilliantly between timelines, genres, and dimensions!

Ionheart will be available wherever books are sold, as a full-color softcover graphic novel (ISBN: 9781603095587) as well as a digital edition, on August 19, 2025. For more information please visit the Top Shelf web site.
