The Mighty Avengers #24

Tied to Marvel's 2009 "Dark Reign" event, The Mighty Avengers #24 presents a striking cover by Khoi Pham and Danny Miki: a figure in the Scarlet Witch's flowing red costume hovers with two blazing orbs of energy at her sides, while a white-haired man in green lunges forward through billowing smoke below her. The tension between the two figures — one ascending in power, one scrambling — sets an ominous, charged tone perfectly suited to a story called "Chasing Ghosts." Dan Slott writes, with interior art from Rafa Sandoval, Roger Bonet Martinez, and John Rauch bringing the drama to life.
