In the chaos wrought by the death of Grendel-Khan Orion Assante, his young son Jupiter--heir to the throne--finds protection with his father's secret weapon: an unstoppable cybernetic paladin of destruction! The story of Grendel Prime unfolds in three tales that form the apotheosis of Wagner's visionary, centuries-spanning narrative: the Eisner Award-winning War Child, with art by Patrick McEown; the riveting Past Prime novel, written by Greg Rucka with pen-and-ink illustrations by Wagner; and the lush, painted Devil Quest, recounting Prime's search through an apocalyptic future for the seeds of his own past. Over five hundred pages of ultra-stylish art and story, culminating in "A Grendel Primer," Wagner's A-to-Z overview of all things Grendel!
