National best-selling author Stef Penney's debut novel, The Tenderness of Wolves, earned her the UK's coveted Costa Book of the Year award. In The Invisible Ones, PI Ray Lovell is on assignment hunting down a missing Gypsy named Rose Janko. Although Lovell only got the case because of his own Gypsy lineage, his blood doesn't blind him to the truth: that the Janko family is hiding a terrible secret. "Another stunner from Penney; highly recommended." –Library Journal
