No Stone Unturned: A Lexi Carmichael Mystery by Julie Moffat

I finished reading this book on 15 January. I really enjoy this series though it is 'fun reading' rather than great literature. It is a kind of romance/spy story/hacker story mix. The main character, Lexi, attracts a lot of trouble and some of her predicaments are quite funny. 

Lexi is a math nerd hacker genius who works in IT security in Washington DC. Her fiancé is a spy/hacker who used to work for the Vatican and now works for the NSA. Some of the books in the series involve travel in Italy, which I enjoy reading about. This latest book includes some fun Dan Brownish kind of Vatican mystique and goings-on.

I'm not giving detail about this particular book as it would create spoilers for someone starting at the beginning of the series. I will just say that the story is about Lexi and her fiancé and how a mystery from the past threatens them and their relationship. 

If you enjoy spy/thriller/romance with a touch of humour then you might enjoy this series. The first book is 'No One Lives Twice'.
