I agree completely with this, but I'm also in favor of reading outside your genre as well. Though I write YA, I just finished The Tiger's Wife by Tea Obrecht (loved it), and am about to start The Art of Fielding by Chad Harbach for my book club. I think reading widely allows you to gain more perspective and opens up new possibilities for your writing. Several women in my book club just read 50 Shades of Grey, and though I'm not sure I want to read quite that widely, I admire their resolve to read
What about you? Do you often read outside of your chosen genre? What was the last book you loved that wasn't in the genre you write?
