Gun Metal Heart, by Dana Haynes

I enjoyed Mr. Haynes' prior novel in this series so much that I was eager to read this, the next episode.  If anything, it was even more fun.   The series features the recurring main character Daria, the freelance spy, and John, the former CIA analyst.   It is not necessary to have read the earlier book to follow this one; there are references to Daria's recovery from injuries and to her relationship with John, but the novel is pretty much free standing.

Here, Daria continues to be chased by the CIA as she seeks to stop a Serbian mercenary group from doing violence and upsetting what little stability exists in the Balkans.

A very enjoyable novel.
