An alien game show. A deadly challenge. The fate of the world is on Astra’s shoulders. Twenty-five-year-old Astra Ching has never sought the spotlight. So when a mysterious black orb appears with a challenge for Earth and selects her to compete in its strange—and very public—game, she’s not pleased to find herself a sudden superstar. The rules are bewildering, and there are no second chances for losers. Yet while Astra fights to stay alive and save the world from imminent destruction, the people of Earth are more interested in tabloids and gossip, like whether or not she’s engaging in a scandalous love affair with a fellow contestant . . . or the mysterious alien known only as Eleven. In her struggle to survive, Astra forms tentative alliances with a handful of trustworthy friends. But as the global gossip seeps into the game and contestants are eliminated with each round, Astra’s celebrity threatens to become infamy and the line between friend and foe blurs. Will she emerge from the arena a hero, or just another headline?

Nasmi Kol was born a slave. Now, she’s a champion. But though she won the seventh game of Headspace, Nasmi has little to celebrate, for her new life may be an even greater challenge. Cast out by her family and world, she has no choice but to take refuge in the orb and become part of the game she hates, traveling from planet to planet to put other alien races through the same gruesome trials she faced. As she reluctantly sows chaos on other worlds, Nasmi—now Seven—finds a strange camaraderie among the other champions, each an outcast in their own right. Yet a cruel fate awaits them all, and the orb is full of secrets, hidden even from those who inhabit it. To protect her family of champions from the whims of the arena master, Seven must take matters into her own hands and change the course of the games forever. But what is the true cost of power and control? The second book in the Headspace series reveals the real story of the arena. Walk the winding halls of the black orb and ask—to what lengths would you go to save the children you love?

First, the gods abandoned the universe. Then, the champions and demigods waged war. Now, Kova has stumbled into the chaos, and she’s far out of her depth. When a black orb arrives on Kova’s planet, it throws her structured and predictable life into disarray. Then her untamable twin Rosi disappears, leaving behind a cryptic invitation to show Kova something extraordinary . . . if Kova can only find her. For years, Kova grieves Rosi’s absence and unsolved mystery. Until a transport launches her away from home and into an interstellar war beyond anything she ever imagined. Inside one of the last living Headspace orbs, Kova comes face-to-face with the final defense against the a tiny band of surviving champions led by a cold, ruthless arena master, Astra Ching. But amid chaos and war, the puzzle of Rosi’s message remains. And though she’s perilously unprepared to face the dangers of this vast universe, Kova will risk it all to see her sister again. Orb Hunters is the finale of the Headspace games—and the story of one woman’s determination to find answers in a galaxy full of questions.
