あなたも殺人犯になれる!

Funny, but that's about it. The main plot twist is revealed in the middle of the book and the rest is a suspenseful watching it play out. I'm a fan of premises where the setting is cut off from everything else and killing starts, but I didn't find it particularly gripping.

The prose is very simple, with no descriptions and an emphasis on dialogue. It's also a pretty short light novel.
