The earliest one I can remember going out and getting as they released was the Wheel of Time series.

Though I definitely completed more series before I completed that one.

All you Need is Kill. (The bases for Edge of Tommorow)

The protagonist loops to the beginning of the day everytime he is killed. So do the aliens.

In the book it plays out less like the “Super Mario Speed Run:” that the movie does. Where everything is the same every time (allowing for some no look kills). And more he just has a ton of hard won experience that means he can deal with the situations as they come up.

There is also a fun sub plot where he is annoyed because he keeps running out of ammo. So he has a sword made from a helicopter blade. Except learning to swing that much mass with an exosuit is suicidal, literally. The mass keeps swinging and you continue twisting and break your back. Thankfully he can still learn from that.
