Three and a half stars, maybe. Reminded me of A Monster Calls in theme and style: A young boy caught up in something bigger than himself. Maybe toss in a little Ragnarok for feel and depth. If you like Gaiman's book, maybe try those others. 
 Man returns to where he grew up and remembers the events of his 7 year old self. The death of a boarder opens something that needs to be put right. However, things don't go smoothly. Engrossing tale. Short book. Go ahead, stay up and read it all. 
 Touch of horror (like any good myth). I liked the perspective. You're getting the kids story, but from the man, so he can see what happened with a little space, even if it's not quite accurate.
