Leif

First off, if you haven't read Existence or Predestined, then don't read this novella. Read those first and then read this. I loved this. It was a collection of scenes from Leif's point of view. Not an entire story, just various scenes that Leif was in from both Existence and Predestined. I admit, there were some scenes that I wasn't sure what they were at first, but that's probably because I read the books so long ago.
It felt like I was able to find out what happened behind the scenes, when we weren't with Pagan and Death, which was really cool. I definitely would recommend this to fans of the series, because it gives you more insight into the story and more insight into Leif's character.
