Heroes Unleashed Books in Order

Kai Wai Cheah's Heroes Unleashed books are superhero thrillers with both feet on the street. They take place inside the larger shared universe of Heroes Unleashed, but the heart of Cheah's corner of that world is one man under pressure. These stories ask what happens when superpowers meet police work, gang politics, public backlash, and family duty.

That man is Adam Song, known in the field as Amp. He is a former Marine and an elite Halo City police operator, one of the Primes in this world, people whose abilities can turn an ordinary raid into a small war. Adam is disciplined, practical, and not interested in celebrity. He treats his powers as tools, not branding, which gives the books a very different feel from brighter, more theatrical superhero stories.

Family matters here.

Adam's connection to Chinatown and his sense of duty to the people closest to him shape almost every choice he makes. In Hollow City, a deadly raid leaves him exposed after he kills the wrong criminal target, and the institutions that once relied on him start backing away. In Unmasked, the pressure gets even worse: his identity is out, he is facing a murder case, and the city feels ready to tip into riots. A bodyguard job at Bright Moon Temple, old military contacts, and supervillain trouble widen the story without losing sight of the personal cost.

The tone is closer to noir and police procedural than classic cape adventure. These books care about warrants, tactics, public optics, chain of command, and what happens after a violent decision. Even when superhuman abilities enter the frame, the questions stay human. When is force justified? What does loyalty cost? How far can someone go before a protector becomes a vigilante?

This is superhero fiction with its boots on the ground.

Because the books sit inside a shared universe, the wider world matters too. Other heroes and villains exist, and events outside Halo City can raise the stakes, but Cheah keeps Adam Song's thread readable on its own. What you get is a grounded take on superhuman fiction, part action novel, part crime story, part moral pressure cooker, with a hero who would rather do the hard right thing than give a speech about it.
