Recs if you like Curse of the Reaper...

books with the aesthetic of a 70s/80s summer camp, where a mysterious killer is picking off teenagers one by one…

We think of summer as the season of light, but shadows are longest when the sun is highest. It is the time of the year when the woods grow too thick to see through, the water grows too dark to see into, and the heat makes the mind play tricks. From the rotting porches of the South to the blood-stained cabins of the North... We call them the Summer Nightmares.

Slasher - a subgenre of horror involving a killer or a group of killers stalking and murdering a group of people, often by use of bladed or sharp tools.

This is a big list of (almost) all slasher books (only first books in a series). As long as there is a killer(s), victims and blood, it counts!
