Challenge of the Super Sons (Challenge of the Super Sons #7)

Here comes Vandal-Savage, here comes Vandal-Savage, right down Vandal Savage laaaaaane (what? He’s immortal! How do we know Santa Claus isn’t based on him somehow?) That’s right, a specter from our boys’ adventure in the past comes searching for them in the present courtesy of the immortal Vandal Savage! Can the super sons defeat him before he deals a killing blow to their friend Rora? And how can they save the Justice League from the DOOM SCROLL if they’re locked in combat elsewhere?
