Orb Hunters (Paperback) (ISBN-13: 9781735903743)

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 demigods: 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.
