Nighttime Is My Time

Multiple characters die as part of the serial killer's plot, which is the central driver of the story.

Injuries and deaths are described in a narrative style standard for thrillers, avoiding excessive, gratuitous graphic detail.

Occasional mild profanity consistent with standard thriller writing.

There are subplot romantic interests for the protagonist, but they are secondary to the mystery.

Threat, stalking or pursuit, uncertainty, and psychological suspense are central and may be disturbing for younger readers.

Contains very mild references to romantic relationships, but no explicit content.

Social drinking occurs as is typical in adult fiction settings.

The book depicts a series of murders committed by a serial killer, though the gore level is kept moderate.
