Ages 12 And Up, Grades 7 And Up

When her sister returns from finishing school a total stranger, a teen seeks out the cause and discovers that the cost of becoming a perfect lady is much higher—and sinister—than ever expected. A lush, gothic tale that will haunt readers long after they turn the last page.

Gwen Donovan adores her beautiful and rebellious older sister, Izzy. But the Izzy who returns from the Delphi School for Girls is not the sister who left for the finishing school. Now she is Isolde: dull and complacent and—most shocking—eager to marry.

Gwen is determined to discover what happened to Izzy at Delphi, and the only solution she can conceive of is to cheat her way into the mysterious school. If she can see for herself what they did, maybe she can get her Izzy back.

But Delphi is far from the finishing school Gwen expects. Several days’ travel away, the estate is the only building on an icy, remote island. Sinister shadows lurk in the hallways, her classmates are strange and secretive, and she is told to never leave her room after dark. More curious, though are the thousands of books, each with the name of a girl on its spine. They line the walls from floor to ceiling, and the students at Delphi are prohibited to read them.

Delphi says they’re reforming the students, but when Gwen discovers a note left for her by her sister, she realizes that what is happening at the school is much more terrifying than she could have ever imagined. There’s something dark at the center of Delphi, and somehow it’s tied to those books—and to the girls who are sent there. And if Gwen doesn’t confront what hides in the shadows, it won’t be just Izzy who’s lost forever.

Story Locale:Delphi School for Girls, a boarding school on an isolated island off the coast of Canada
