The Man Who Died Seven Times by Yasuhiko Nishizawa

 

This is a kinda neat little mystery novel, with just a touch of weird in the premise. Plays mostly fair--the POV character, a first-person narrator, has some apparently wrong ideas about the sequences of events. It's one of those novels laden with mostly despicable people, if I were the narrator I'd want to be completely shut of the family; but he's a better person than I am, he works to prevent his grandfather from dying. The characters are moderately distinct, you get some sense eventually for who's who and what's what, but it takes several times through the loop before you get all that worked out (at least, it was several times through the loop before I did, I found all the names and characteristics kinda confusing, but I might be an idiot). This is definitely an unhappily unique unhappy family, but the prose--at least the translation I read--was breezy enough to make it a reasonably pleasant read.
