In the Elite Hunter Command's latest clash with Othersiders, the army of monsters nearly wiped them out. Apex City is safe-- for now. But within the city barriers, the corrupt and powerful PsiCorps is determined to usurp the Hunters as chief defenders of Apex City and Joy is now squarely in their crosshairs. There are few she can trust-- not even Josh. But Abigail Drift, the head of PsiCorps, is testing experiments designed to empower PsiCorps and render Hunters superfluous-- a scheme that's already killed off dozens of Psimons. Joy manages to smuggle Josh to safety, but he cannot evade Drift forever.
