When a planet has days left to live, how far would you go to save everyone you love? Jake Rose is racing across the galaxy on a suicide mission. His destination: Rison, a volcanic planet that will implode in mere days. His goal: find the umjaadi starfish that holds the cure to a deadly plague killing both his girlfriend Em and Earth's ancient water people, the Phoke. No pressure. Aboard the starship Eagle 10, Jake and his crew have perhaps the worst timing in galactic history. They're arriving on Rison just as the planet tears itself apart-earthquakes splitting continents, oceans boiling, and millions of desperate Risonians fighting for spots on the last evacuation ships. But Jake's foster father, a high-ranking Risonian official, refuses to help. Local politicians see the Earth mission as a threat to their own escape plans.

And somewhere in the chaos of a dying world, one small starfish holds the key to preventing three species from going extinct. Jake's new ally, Utz Seehafer, knows Rison's waters better than anyone. But Utz has his own impossible mission: save his brother Derry and their beloved great white shark, Godzilla, before the planet's core collapses. As volcanic eruptions rock the ocean floor and time runs out, both boys must choose between personal loyalty and the survival of entire civilizations. Because when a planet is dying, heroes don't get to save everyone.
