Horror sub-genre: Cult, Psychological 

Plot: After his last case leaves him as an amputee, retired detective Kline is having a rough time adjusting to his normal. Then a cult of amputees kidnaps and enlists him to solve a murder on their compound.

Review: ⭐⭐⭐⭐1/2
This is genuinely one of the weirder horror books I've read, but despite its bizarre subject matter I found it really creative and engaging. Kline is pulled into a cult he wants no part of and somehow it just keeps getting worse for him. As an avid reader of the horror genre it's always nice to come across something totally unique.
