The Invisible Ones

The Invisible Ones, by Stef Penney, 399 pages

Ray Lovell is a private investigator.  He is also half-Romany, which makes him the only option for investigating the disappearance of a young Gypsy woman who hasn't been seen in years.  The travelling community is a tight-lipped one that doesn't take to strangers of any kind, making Ray's investigation harder than it should be.  But as Ray gets closer to the truth, he realizes that young Rose Janko's disappearance is the least of the mysteries he must uncover.  This was an acceptable mystery, with an ending that wasn't obvious.  There are also some interesting insights into the British travelling community.
