Carrie Hauser's life is a little crazy right now. Her parents have just gotten divorced, her mom has uprooted her to the town of Kingsport, a lethal high-tech mercenary wants her dead, and a group of teenage superhero wannabes need her help taking down a rogue artificial intelligence threatening to wreck her new home. What's a girl with super-powers to do?

The world is full of magic…and it wants the Hero Squad dead. Winter in Kingsport heats up when the necromancer Black Betty comes to town, on the hunt for the Libris Infernalis, a legendary book of dark magic with the power to raise hell on Earth...literally. Facing power beyond their understanding, the Hero Squad turns to the Protectorate’s resident sorceress for help, but the mysterious Dr. Enigma seems to have an agenda of her own. Is she on the side of angels, or is she a devil in disguise?

The past is coming back to haunt the Hero Squad. Archimedes, the Squad’s first foe, is finally heading to trial, and the teen heroes aren't exactly looking forward to again facing the man capable of revealing their deepest secrets to the world—but their secrets are nothing compared to the dark truths being hidden from them by people they know and trust. When those secrets are finally laid bare, they could tear the team apart, one heartbreaking piece at a time…and if they don’t, the bloodthirsty killer known as Buzzkill Joy will.

His name is uttered in terrified whispers. He’s the bad guy the good guys fear. He is the King of Pain, and he’s come to Kingsport to put another hero in the ground. The Hero Squad faces their deadliest foe yet, a mysterious killer who hunts within the superhuman community, leaving dead bodies and broken minds in his wake. The Squad is next on his hit list, and the King of Pain will push the young heroes to their absolute limit—and one of them might not survive the experience. Get ready for the darkest chapter in the Action Figures saga as the Hero Squad prepares for the greatest fight of their lives—a fight in which there are no winners…only survivors.

The Hero Squad is finished. Their friendships damaged in the wake of the King of Pain incident, perhaps beyond repair, the team go their separate ways to lick their wounds and figure out where their respective paths will take them…and if those paths will ever lead back to each other. "Team-Ups" features a series of individual adventures that partner the Hero Squad with unexpected friends and pit them against some surprising foes. Sara finally learns the price of her betrayal; Matt and Nina Nitro go hunting for superhuman fugitives; Carrie gets a rematch with Manticore that takes a shocking turn; Stuart follows Dr. Enigma into Boston’s magical underworld in search of a powerful and dangerous artifact; Missy gets a lesson in taking names and kicking ass from the Entity; and it all leads to Carrie finally learning the truth behind her fantastic powers…but is she willing to pay their terrible cost?

One of our super-heroes is missing. It took a devastating attack on Kingsport to reunite the Hero Squad, but their reunion proves short-lived after Lightstorm vanishes following the battle, leaving the team without its most powerful member at the worst possible time. Damage Inc. is back and more dangerous than ever, thanks to the mysterious mastermind known only as the Foreman arming them with enough firepower to take on the Hero Squad—but for what sinister purpose? The Squad is determined to find out, but the answers could cost them dearly. Psyche takes center stage for this game-changing chapter in the Action Figures saga, which includes the bonus short story, Action Figures – Live Free or Die. This is when everything changes!

On Earth, Carrie Hauser is a hero. But on the far side of the galaxy, she’s just another soldier on the front lines of an interplanetary war.
