Homecoming. Starfire Angels: Forgotten Worlds, #17

When Nya and L'Ni visit Inar'Ahben, they soon discover that threats against the Starfire still lurk on the Inari homeworld. Although the Shirukan were defeated more than ten years earlier, they are no less a threat to Crystal Keepers. No one is more aware than Security Chief Rajeun Leksel, but even he underestimates the determination of the remnants of the former Shirat Empire. In Nya, the Shirukan see the opportunity to retake what was once theirs.
They will stop at nothing to obtain a Starfire shard and complete their plans for domination. Nya must overcome her worst nightmares against an enemy who understands the power of the Starfire too well.
