Greetings! I'm new to the group and feel weird about asking for suggestions without first contributing. But I'm running out of stuff to read! I'm a long-time science fiction reader with 50 years of sci-fi under my belt. I've read all the classics and read or tried the top 100 science fiction books on GoodRead's Top 100 list. (Some were terrible and I gave up on them.) I love almost all the sub-genres though I'm a little tired of dystopian. Lately I've been wandering through some space opera, reading the latest Old Man's War and whipped through The Culture. Enough background. My question: What new or old novels can I read that both draw me in and add some science to the fiction? I want to challenge myself. Suggestions?
