**At the Threshold of Tenderness — or Terror** Isabel's life was suddenly glorious. Her Aunt Camilla welcomed her to her new home. Her boyfriend, Matthew, would make her life complete. But frightening things began to happen at Camilla's — strange parties, midnight meetings in the woods, dreams — or were they dreams? — of being ravished by someone Isabel could scarcely remember in the morning. Then, after one of her nightmares, she turned to Matthew for comfort — only to recognize the glitter in his eyes! Only to realize the horrible truth she was born to discover!
Severity reflects intensity, not value — “central theme” means a warning is a core part of the book, not that the book is bad.
