George Pérez's Sirens #5

The penultimate chapter of George Pérez's six-issue series arrives with a cover that crackles with energy — a dark-haired warrior in black armor locks blades with a towering armored figure whose orange-and-silver suit radiates an explosive burst of light, while grotesque figures loom in the shadows and a glowing green face watches ominously from the corner. Pérez's linework (with colors by Vladimir Popov) gives the confrontation a kinetic, almost dimensional quality, as if the collision of these two fighters is tearing reality apart around them. With only one issue left after this, "Book Five: In and Out of Time" promises all the intricate, densely layered storytelling that has defined this ambitious BOOM! Studios saga.
