Hi!! Thank you so much for this opportunity:) the most recent spooky book I’ve read was The Last House on Needless Street, it wasn’t really spooky, it was more of a suspense novel. I was really intrigued 
Mrs. March was my favorite recent spooky read. So creepy.
Definitely Stephen King’s It
I agree that Stephen King is the best at this genre. And his best is 11/22/63.
The spookiest book I’ve read was Baby Teeth. It was more psychological but the baby was spooky 
The Sun Down Motel was a recent favorite.
Rebecca by Daphne DuMaurier
I really enjoyed There’s Someone in your House!
Summer Sons by Lee Mandelo
The Wicked Deep by Shea Ernshaw
I loved The Whisper Man, so very excited about The Shadows!
The Dark Descent of Elizabeth Frankenstein was a touch spooky in the sense that it was such a wild and gruesome story by The Only Good Indians by Stephen Graham Jones had moments I had to stop reading at night because I knew my mind would run away with things.
I always enjoy Riley Sager and Karin Slaughter
I read The Last Thing He Told Me recently and enjoyed that.
Lock Every Door by Riley Sagar!
And The Trees Crept In. It was my first ever spooky read as a middle schooler and I could not sleep!
Misery by Stephen King, Mexican Gothic by Silvia Moreno-Garcia, and House of Hollow by Krystal Sutherland are a few of my favorite spooks!
John Saul’s When The Wind Blows is my favorite spooky read!
Ruth Ware has some of my favorite spooky reads
The Woods Are Always Watching by Stephanie Perkins - scary and spooky as well as shocking.
