Sentinels of Justice: The Calm Before the Storm
by Doc Quantum, CSyphrett, John M. Burt, and Blackwolf247, with Punkybluester 
The Crisis on Infinite Earths that threatened Earth-4 is over, but it left the Sentinels of Justice scattered, the action-heroes each preoccupied with their own problems. Son of Vulcan has been appointed with his new duties as the overseer of the world from Mount Olympus, but where does that leave John Mann? Captain Atom was granted power and virtual immortality, but was that at the price of being truly human? Nightshade’s main goal in life has always been to rescue her brother Larry from the Land of the Nightshades, but can she do it without needing rescue herself? The Blue Beetle finally returns to Pago Island to face up to his past, but will he be able to bury it? The Question fights a never-ending battle against corruption in Crown City, but how will he react when two rookie action-heroes begin fighting crime in his city? Will it take a threat to the time continuum itself by six criminals from the future for the core members of the team to reunite and start over once more? Guest starring Phantom Lady and the Mysterious Traveler, and featuring the first appearances of Blue Beetle IV, the new Black Fury, and Street Hawk.
