The Fantastico Portal (Stanley Pargo in Suburbia #2) by C.L. Clark

A dark and humorous tale for teens and adults. Stanley Pargo has only just arrived in Suburbia, and already, he wants out. The principal of his new school is a monster of tyranny, and Stanley’s teacher is even worse. Every day, she conceives new and terrible ways to torment him—each one worse than the last and all with a single goal in forcing Stanley to learn his place. But, Stanley isn’t like other children, and he soon suspects the perfect community of Suburbia isn't at all what it appears to be. Instead, it seems to be changing the adults in odd and awful ways, but little does Stanley realize that as bad as Suburbia is, a far more dangerous foe still lingers outside its walls. This is book two in the Stanley Pargo in Suburbia series
