A quick read, kept me turning the pages. There's some minor issues with characters talking followed by a capital: "Blah, blah." She said, instead of-- "Blah, blah," she said. Sometimes an action other than speaking also follows the speaking part, "Blah, blah," she walked away.
It wasn't noticeable until the last page. The story moves along quickly so the minor anomalies are easy enough to ignore.
I'd classify this as horror, rather than suspense. If you like a good vampire scare, this qualifies.
