Are book titles with hashtags like #GIRLBOSS the next publishing trend?

I explored the trend of book titles like #GIRLBOSS, #scandal, #YesAllWomen and #Berlin45 the next big thing in publishing? I explore the topic in my first piece for The Guardian US. I love getting the opportunity to write about books and learned a lot about marketing savvy from those I interviewed, including Sophia Amoruso, Nasty Gal CEO and her editor, and young adult novelist Sarah Ockler.
