Collects Iron Man (2012) #23-28. An all-new epic begins! Malekith the Accursed, lord of the Dark Elves, has a problem with Iron Man. Then again, Malekith the Accursed has a problem with pretty much everyone on Earth. And when Malekith the Accursed strikes, blood will flow and darkness will fall...unless Iron Man can gain the upper hand! It's cutting-edge mortal science versus the most arcane Asgardian science imaginable...all in a bath of blood. Plus: which classic Marvel UK character returns in a reinvented form after the events of Revolutionary War? And how do the Mandarin's rings factor into this crisis? Iron Man vows to get to the bottom of things...assuming he lives!
