Booster Gold (2007 DC 2nd Series) #41
Written by KEITH GIFFEN & J.M. DEMATTEIS Art and cover by CHRIS BATISTA & RICH PERROTTA
A new threat from another time attacks Booster again - for the first time! Unfortunately, this threat catches Booster in Rip Hunter's lab, and the bunker takes enough of a beating to put everybody out of time-traveling commission for a long while!
