I haven't forgotten about you, 30 Day Book Challenge. Today is day 12: a book you used to love but don't anymore.
I wouldn't say there are books that I used to love and don't anymore. But there are books that I used to be obsessed with and have outgrown.
All of R.L.Stine's books. I used to read Goosebumps to my little sister. I was obsessed with all the Fear Street books, especially the Fear Street Saga. I think the Fear Street Saga was what made me interested in historical fiction. They're great books, just made for a slightly younger audience than the late-20's I am now.
