In this second outing Ellie is up against a disturbing serial killer who seems intent on making things personal. Lines from her own poems and post its addressed to her are found at each scene and she and Delta team find themselves drawn into a confusing and fast moving case. The bodies are piling up and the clues refuse to connect. The only thing that she is sure of is that somehow it connects to her and the Butterfly Foundation.
During all of this Ellie's always slightly loose grip on reality is slipping further, of course with her obsession for 80's TV shows and music I was once again treated to a walkthrough of my own childhood via theme tune. I love it. If you are too young to know who Hawkeye and Radar are then you need a note pad and a card for the video store. Oh and of course it's only a matter of time before Gibbs gets referenced.
The romance between Ellie and Mac has settled into comfortable and charming and less time is given to introducing you to her team in this one. There is an argument for reading the first book first, but it's not absolutely neccessary if you are willing to take the authors word for it.
Cat's writing is getting stronger, this book is more complex and more tense and emotive than Killerbyte. The lightness and fun are still in there though so it never becomes too dark. I love these books, they are the perfect literary answer to NCIS, Bones, Criminal Minds and so on. Other people have to read this I need someone to talk to about it and I really can't risk spoilers!
