Green Lantern: Emerald Warriors #6

The massive Red Lantern symbol dominates this striking 2011 cover by Rodolfo Migliari, while a gravely wounded Red Lantern — bleeding from the chest and hand, her costume torn — tumbles helplessly in the foreground, framed by shattered, bone-like constructs radiating outward. It's a visceral, unsettling image that sets an appropriately dark tone for "Last Will," the sixth chapter of Peter J. Tomasi and Fernando Pasarin's Emerald Warriors run. If you've been following this series, this cover alone signals that the stakes have risen considerably.
