I've been in a horrible reading slump for years. I was fine with audiobooks and podcasts but just couldn't concentrate on reading.
Finally I've found that Agatha Christie novels hold my attention - they are fast paced, not overly complicated, and got me interacting with the story as I played detective while taking notes on the clues in the story.
Now that my reading muscle memory is coming back, I'm able to branch out to more complex books.
Good Omens by Sir Terry Pratchett and Neil Gaiman is a classic, once I finished it I got into American Gods by Gaiman and then into Pratchett's Discworld series
The experience reading Good Omens when I was younger is one I want to capture again. I had so much fun and the pages flew by. I like the current series on Prime also.
I had trouble with American Gods for some reason..like my mind kept wandering and I wasn't that into it.
I did like the Guards! Guards! Discworld book...you just reminded me they exist!
