Re-reading is my safe place
There are a lot of times that I will be reading a good novel and then it will get to a point in the plot that doesn't mix well with a lot of the things that are happening in my real life. Its typically to do with war, the worse parts of human nature, etc., so I have to put it down for a while.
That's what happened when I was about 1/3 the way through Cibola Burn and then I went to American Gods, something that I have read before. I wasn't quite ready to go back to that books so I went through the Murberbot Diaries, which are awesome, and gave it another try.
Then I could tell where the story was going and I wasn't ready, still, and read In the Garden of Iden and made my way through it. I wasn't a fan so I didn't start oany of the other books in The Company series, and decided to give The Collapsing Empire a go, then a major turning point happened early on and I moved on again.
I read Project Hail Mary which was awesome and now I'm re-reading the Old Man's War series. Its like a comfortable blanket, one that I would love to see expanded to understand more about the political structure of the Colonial Union before the Conclave, but I can understand why an author may get tried of an universe and want to move on to new ideas.
This is your permission, like you need any from me, to go and re-read that favourite book guilt free.
