In total contrast to the epic sprawl of a book like It, my last King before this one, Gerald's game is mostly set in one room with one character who is handcuffed to a bed after her husband dies pre-sex game. Jessie suffers intensely as she tries to free herself. Jessie is menaced by external enemies, her own body the longer she stays frozen in the cuffs, and voices in her head from bad childhood memories. 
 This book is legitimately disturbing to the point where I had a Gerald's game themed nightmare after reading it before bed one night. Has both creepy scares and over the top gross out horror. Very tense at points and gripping. I think it is a touch too long and some of the protagonist's inner dialogue is a bit tin eared but beyond those minor flaws this is a really worthwhile read. Super unsettling. Underrated.
