Zombies are people, too

"A zombie escapee is recaptured by the top-secret government agency that created him. The smartest kid in the fifth grade, Arnold Z. Ombee (a zombie, obvi), uses his superintelligence to tutor a struggling classmate. Now Arnold is accepted--maybe even popular. But it's not just the cool kids who have their eye on him. Arnold catches an oddly familiar man spying on him and his human family, the Kinders. Soon after the encounter, the police inform Arnold's school that an 'undocumented fugitive' is in attendance. The man--a Dr. Grassmere--convinces Arnold's family to let him take Arnold back to the Territory for a week of testing. But the 'tests' serve a more sinister purpose: brainwashing Arnold and his 'fellow afterlifes' andturning them into superstrong zombie warriors! Will Arnold snap out of it and remember his human life? Or is it already too late?"--Provided by publisher.
