The Invisible Ones / Stef Penney 399 p.

An excellent missing persons thriller, and so much more. Ray Lovell is a private investigator of Romany descent hired to find Rose, the wife of the son of a prominent English Romany clan. Told in alternating chapters from the point of view of Ray and JJ Janko, the nephew of Rose's husband, the plot has some amazing twists, including a family curse and a mysterious genetic illness. Like most Americans, I know almost nothing about Romany culture, which added to the interest this book held for me. Strongly recommended.
