"The Justice League is dead. Manhattan is destroyed. And somehow it's all Flash's fault. A mysterious attacker keeps targeting the Flash and those around him, blaming Flash for his family's death. But besides doling out death and destruction, the attacker's mysterious weapon provides one more thing: a second chance...Every time Flash comes into contact with the weapon's energy, he finds himself flung further back in time. But can Flash and Batman solve the mystery and save the city before time catches up to their destruction once more? Plus, the Justice League faces off against microscopic invaders, crazed super-soldiers and Mera, Queen of the Sea!"--Page 4 of cover.
