Metamorphis Island 3 - The Math Test: Rehabilitation Through Domestic Discipline

Callie had always hated math. If they'd told her she'd have to take math on the island, she'd never had agreed to come here. To make matters worse, their math teacher had threatened to spank them with his ruler if they didn't meet his exacting standards.

Metamorphis Island is an experiment in rehabilitation. Young adult girls convicted of petty crimes are given the option to serve out their sentence on the island instead of the state prison system. Living in loving families and made to attend school, the girls are subject to corporal punishment as needed to help them develop into healthy young adults, capable of living a life free of petty crime.
