Can an anxious eleven-year-old find her chill and save her family from creepy aliens? Only if she's the most awesome, super-brave astronaut since Spaceman Spiff! So take a deep breath, grab your sidekick, and blast off with Jillian to Parasite Planet.

Eleven-year-old Jillian hates surprises. Even fun ones make her feel all panicky inside. But, she's always dreamed of joining her space-explorer parents on a mission. It's Take Your Kid to Work Day, and Jillian finally has her chance to visit an alien world!

The journey to Planet 80 UMa c is supposed to be just a fun camping trip. But then the local wildlife starts acting really dangerous. Only the onboard computer SABRINA sorta knows what's happening—at least when it's not goofing off or telling bad jokes.

Looks like it's Jillian versus Parasite Planet—and Jillian is determined to win!
