All You Need is Kill

Keiji Kiriya is a young recruit in the United Defence Force. He's cannon fodder in a war against a merciless alien race of invaders. Over-matched and lacking combat experience he takes fatal damage and dies. And then he wakes two days earlier with full memory of his death.  
Hiroshi Sakurazaka's military sci-fi novel is translated from Japanese here. And it translates pretty well. I don't know if its big screen transformation (Edge of Tomorrow with Tom Cruise and Emily Blunt) is as smooth because I haven't seen the movie yet but I'll definitely take a look now.
I had a fun time reading this one. You'd think a sci-f story about a soldier endlessly reliving a couple of days that ends in a big battle would get boring after a few spin-cycles. These sorts of stories with a groundhog day angle can be tricky. Hiroshi Sakurazaka keeps things fresh though, never forcing us to relive things in a repetitive way but skilfully follows our hero's attempts to break free of his situation. Although you'd expect the narrative to be chock full of bomb's and bullets the battle is sketched over with more focus on Keiji's personal development and his relationship with the only other looper Rita Vrataski, the Full Metal Bitch being the order of the day. It's a shame that Keiji and Rita are the only fully developed characters in the book though.
