Titans. Vol. 4

"When a series of mistakes by the Titans nearly leads to global catastrophe, the Justice League steps in to issue a directive--Titans no more! While Donna Troy is kept under observation in the Justice League's watchtower to determine the link between Donna and her evil future self, Troia, the rest of the team is told to stand down and take a break. That doesn't sit well with Arsenal, though.

Seemingly abandoned by his friends, Roy Harper pushes himself right to the edge to track down the source of a dangerous new street drug...even teaming up with his deadly ex, Cheshire. But while Arsenal may be in over his head, his investigation reveals a worldwide threat that even the Justice League proves unable to stop! Now it falls to the Titans to save the world from destruction. And while they're no longer a team, they are still a family...but will that be enough to unite them? "--.
