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!
