The book follows a new mission, where AstroWolf, LaserShark, SmartHawk, and StinkBug must find a planet fit for human life after we've finally made Earth unlivable. After they splash-land on the Water Planet, they find power-hungry clams, a rebellious underwater force, and a world full of too-good-to-be-true. Can this aquatic world really be humans' new home? And why are these clams so eager to swap planets? AstroNuts Mission Two is full of laugh-out loud humor with a thoughtful commentary on the reality of climate change at the core of the story. Eager and reluctant readers alike ages 8 to 12 years old will be over the moon about this visually groundbreaking read.
