This one is about books that made an impact on us. It started as "books that changes our lives" and became more like "books that changed how we feel about books." I'll just call it "books that made an impact." Although there will be some overlap for top-books-ever lists we've made, these lists include some surprising entries.
We each picked 10 independently. Our lists are below and include only two overlaps (one of them being The Watchmen, which gives me a reason to post this trailer!).
