Jillian joins her space-explorer parents on a mission. When killer worms attack their base, it's up to Jillian and her hyperactive computer SABRINA to save her parents from the creepy aliens.

Nicole Kornher-Stace is the author of the Norton Award finalist, Archivist Wasp, and its sequel, Latchkey, which are about a postapocalyptic ghosthunter, the ghost of a near-future supersoldier, and their adventures in the underworld. She has two more books due out in 2021: the sci-fi thriller, Firebreak, and of course, Jillian Vs. Parasite Planet. You can find Nicole on Twitter, where she is probably semicoherently yelling about board games, video games, hiking, aromantic representation, good books she's read recently, or her cat. She lives in New Paltz, New York with her family.
