These are really in no particular order.
I think this actually came out in late 2010, but I read it in 2011, and LOOOVED it! Plus, I was not a fan of Rock Hard which did come out in 2011. Hey, it's my list!
Caressa's Knees, (Comfort Series #2) by Annabel Joseph
I loved how bratty Caressa was! The relationship between the two main characters was fascinating. They pushed/pulled each other throughout the book which made for a wild read.
Maid for It, by Lucy Rodgers
Maid for it is centered around a clever premise that makes the dubious consent storyline work well. I can't wait to read more of Lucy Rodgers' work.
The characters are so interesting that the story is much more than just steamy sex.
