Spooky SFF Reads Like Last to Leave the Room

It's grim outside, and these books are even grimmer.

Last to Leave the Room Collage

While the magic of other realms may fade, true horrors exist every day. Just take any scientific invention ever and consider how terribly it could go wrong. You’ll never run out of things to hide beneath the covers from. So, when I heard about Caitlin Starling’s latest book, Last to Leave the Room, I knew I had to have it.

Here's the premise: San Siroco is sinking. That much Dr. Tamsin Rivers, head of the research team knows. But for some reason, her basement is sinking faster. It’s a problem she can’t solve. And one she quickly becomes obsessed with. But when the dimension of the room change and a door appears, everything changes. Behind the door is an exact replica of Tamin. Only, where Tamsin is calculating, arrogant, and cruel, this other is kind, sweet, and compliant. It looks human. Acts human. And passes every test Tamsin can think of. But the longer it exists, the more of Tamsin’s life starts fading away. As her world falls apart, Tamsin has to figure out what her double wants and where the door actually leads.

Last to Leave the Room is a fascinating combination of horror wrapped in plausible science. Can a basement sink faster than a city? Maybe, maybe not. Or is the science in who we are and who we might be if faced with our alternate selves. Is the double a clone? An alternate self from another universe? Or perhaps simply a creation of a fractured mind. It’s a journey into the terrifying side of science and one I cannot resist. If you are looking for more terrifying science fiction, here are nine spooky STEM reads that promise to keep you up all night.

After the first expedition reported an environment akin to Eden, it was hailed a success. Until the second expedition ended in mass suicide. And the third in a bloody hail of gunfire. Each expedition led to failure and death. Now, it’s time to try again. The twelfth expedition is made up of four women: an anthropologist, a psychologist, a surveyor, and a biologist. They have to map the terrain without being contaminated with whatever led to the last ten failures. But each woman carries a secret, and those might be deadlier than whatever is inside Area X.
