Slippy’s cousin Gem wants time apart from her twin brother I.Lo but he doesn’t want to hear it. His stubbornness causes her to lose a game of capture-the-flag. When no one wants to investigate the super puff planet they discovered, Gem races off on her own, despite the very high temperatures and strong winds. Ella explains to a confused I.Lo how Gem is feeling. Gem and I.Lo finally come to an understanding. They will always be twins, but they are also their own people. 

The year is 3021. The place is the Milky Way, where eight-year-old Ella gleefully heads out with her friends on exciting adventures of discovery. At only eight, she already knows quite a bit about space... but there is always more to explore!
