The Zero Planet II. The Zero Planet J wolf and J Panther

Earth is behind them. Twenty-six survivors have escaped a dying world aboard a massive Ark, carrying the last fragile hope of humanity into the unknown. After a long journey through space, they finally discover Zielonor - a mysterious world of lilac landscapes, brown valleys, rivers, lagoons, and a species unlike anything humanity has ever encountered. The inhabitants of Zielonor are powerful, intelligent, and deeply suspicious of the strangers who have fallen from the sky.
Humanity wants a place to survive. Zielonor wants them gone. But when an ancient enemy threatens the planet, humans and Zielonori are forced to fight together. Seven humans will pay the ultimate price, and a fragile alliance will emerge from the ashes of war. Yet Zielonor holds secrets far older than humanity. Beneath its surface lies an ancient mystery. A gate.
