Military: Skirmish
Now with both Perimeter and Cryptix after them, Jorie, Atticus, Trey, and Bry need to lay low. Upon hearing Jorie's mother on Xeros is deathly ill, the solution becomes clear. They make a deal with a pair of local pirates to escape the planet.
To save Jorie's mother, Trey reconnects with childhood friend Twelve and faces his past as an Emerald Legion test subject. The four are able to destroy the Legion facility, free the remaining test subjects, and get the needed medicine.
Jorie gets to the bottom of her mother's illness, and finds proof Blue Spire Academy president Norah Everdin is behind deadly, unethical experimentation on BSA staff and students.
