Let Me Tell You How I Died (Point Horror) by Sinclair Smith - Vintage Paperback

Delia can't stop reading the old diary she's found. She's becoming more and more like the girl whose words she reads---seeing the world through her eyes---even having her memories. Soon she believes she was the girl who wrote the diary---in a past life.

So does her killer.

The terror is alive once more. For the girl who wrote the diary was murdered. And whoever killed her the first time...is after her again.
