With the public watching their every move, the Teen Titans struggle to find common ground in time to save Jump City from an extra-terrestrial threat out to reclaim what was stolen from them.

When Joker comes to Jump City in a mad scheme to bring Robin home to Gotham, a reign of terror unlike anything they've ever seen before sweeps the city. Robin goes off the grid to meet his past head on, and it's up to Starfire to unravel the clues he's left behind to get to him in time to save him from his old enemy.

Sequel to Foundations. More than a year has passed since the rescue in the Citadel, but when the public finds out the Psions came searching for Starfire they demand she be banished. Meanwhile, Batman's negotiations to keep Tamaran at bay prove futile when a suitor is selected for her hand. Knowing their fate if Starfire leaves, can Robin let outside forces tear the Titans apart?
