Invisible Murder is the second installment in the Nina Borg series and I enjoyed it quite a bit more than the first.
In this installment, Nina isn't as "bleeding heart" or annoying (I was a little tired of her by the end of the first book - so many irritatingly irresponsible decisions)! She definitely felt more "real" this time and not as over-the-top with her actions and she garnered more sympathy from me as the reader.
This story, like its predecessor, had many characters and the chapters bounced between different sets' of characters point of view. The authors tell the story well this way - keeping the reader on his/her feet, never giving away quite enough until the very end!
One of the aspects I like about this genre, Nordic Noir, is that it is often based on crimes against humanity and how easily it is to fall into the trappings of that dark world - it isn't always the most obvious of suspects.
I also enjoy the foreign aspect of the story and the setting. The authors do a good job of bringing the world to eyes that may have never seen it personally.
After the first book, I wasn't sure that I would continue very far into this series; however, after this book, I plan to follow these authors through for more!
