Losing Christina Series by Caroline B. Cooney

The Shevvingtons are perfect. Mr. Shevvington is the charming, handsome principal of Christina's school. His wife is a dedicated English teacher. When the Autumn fog rolls over the coast, Christian and Anya begin boarding at the Shevvington's home, where Christina discovers that nothing is as it seems. Anya is slowly losing her mind, and Christina knows the Shevvingtons are behind it. But who will take her word against that of the Shevvingtons? This is book one in the Losing Christina series.

Outside, she could freeze.Inside, she could die. Everyone says Mr. and Mrs. Shevvington are lovely people. But Christina knows otherwise. She sees what they are doing: First, they chose Anya. Then, Christina - but Christina was too strong for them...so now it's Dolly, sweet, trusting Dolly. Poor Dolly. Everyone thinks she is outside somewhere, lost in the snow storm. But Christina knows Dolly isn't outside. She's inside. Lost somewhere in the Shevvingtons' house. And that's much worse.

Christina knows the Shevvingtons have left a trail of hollowed-out, lost girls in mental hospitals across the country, and she has seen the secret files that prove it. But the Shevvingtons are determined to destroy the evidence ­ and Christina. This time, they'll use fire. They stuff her pocketbook full of matchbooks, scribble flames over her class notes ­ anything they can do to make it look like Christina is obsessed with fire and a danger to herself and others... moreChristina knows the Shevvingtons have left a trail of hollowed-out, lost girls in mental hospitals across the country, and she has seen the secret files that prove it.
