Finn Caspian, his three best friends, and his robot Foggy are excited to explore a brand-new planet . . . until Finn's mom makes them bring along an annoying new robot named Voltronix Zu.

Blast off into a brand-new adventure inspired by the popular award-winning kids' podcast! Like the podcast, the books are sort of like Scooby-Doo meets Buffy the Vampire Slayer in space. The story centers on Finn Caspian, an 8-year-old boy aboard The Famous Marlowe 280 Interplanetary Exploratory Space Station. He and his friends Abigail, Elias, and Vale are Explorers Troop 301, taking off from the Marlowe to explore uncharted planets, help the occasional alien, and solve a mystery that threatens to destroy the Marlowe.

The books in this series are for kids ages 7 to 12 looking for a funny illustrated story to tear through. They contain no violence, a little bit of suspense, and some aliens who are real chuckleheads...
