Nightfall

Readers who enjoy gradual suspense may welcome that patient build; others may prefer a faster start.

The plot includes a creature capable of possession and an explicit intention to kill Elena. Consider whether supernatural menace and a threat to a character are comfortable material for your reader.

If the suspense builds gradually, what clues or changes in atmosphere help you notice that the situation is becoming less certain?

Try a short shared reading check-in early on: ask whether the developing pace is holding your reader's interest, and adjust the reading rhythm or take breaks accordingly.
