If You Liked "Fifty Shades of Grey"

I haven't read the mega-bestseller Fifty Shades of Grey. So when a patron asked for similar books, I saw the Hennepin County Library in Minnesota has a list "If You Liked Fifty Shades of Grey," with titles we have in our AADL collection including Kushiel's Dart and Slave to Sensation. The Minnesota list comes with this warning: "Steamy reads. Be careful of scalding if you open the covers of the books too quickly."
