Invisible Murder - Lene Kaaberbøl, Agnete Friis This book simply couldn't keep my interest. In my Nordic Noir group, I think I have determined why I can take or leave the character of Nina Borg. Unlike most in the Nordic Noir genre which are police procedurals, I consider Nina Borg, who is a nurse, to fall more into the lines of medical thrillers which NEVER keep me entertained. The writing is good, but I am not tickled pink by the character. So, if you are into the standard of Nordic Noir, just know that you won't be going into that in this series. I compare it to Tess Gerritsen's medical thriller books.
