About the Book
For the first time ever, the Smithsonian’s iconic Hope Diamond embarks on an historic journey to Los Angeles for a noble cause. When the priceless gem disappears at a celebrity fundraising gala, Security Expert Hope Diamond and FBI Special Agent Matt Dennison must navigate the glamorous, yet treacherous, world of gem collecting, where every facet of the case holds a new clue, and murder lurks around unexpected corners.
About the Reviewer
I was sent an advance copy of a review by D. Donovan, Senior Reviewer for Midwest Book Review, with permission to publish at any time. This is a quote about Donovan from a Peace Podcast. “Donovan has been reviewing books for over 35 years. She is the most thorough, elegant and sought after reviewer according to hundreds of testimonies.”
Review of Diamond and the French Blue
“Diamond and the French Blue is the third book in a cozy mystery series featuring the partnership and intrigue confronting Hope Diamond, the founder and head of Diamond Security, and FBI Special Agent Matt Dennison. Familiarity with the prior books in the mystery series is highly recommended for a fuller-bodied feel of character development as Hope finds herself immersed in political ambition and deadly surprises.
“Karen Gilleland provides a thought-provoking, astute inspection of political strategies gone awry as Hope and Matt become immersed in a new situation that places Hope in the position of being a potential victim.
“Special permission has been granted for the Hope Diamond to leave its secure home. Now Hope is charged with keeping it safe against all odds and influences.
“As the Hope Diamond and Hope’s future become inextricably linked, readers will revel in the sense of threat, discovery, and new opportunities that Hope and Matt face in the course of engaging in some dangerous moves for the sake of greater good.
“Also at stake is their evolving relationship, which comes with questions and serious considerations:
“‘Matt, who had been getting Frank’s beer, felt a pang of jealousy. He liked Frank, but when he and Hope were together, Matt felt like an outsider. It wasn’t only Frank. Matt would have to come to terms with her business and whether he could totally support her, which he would be bound in conscience to do. Until now, he never doubted that it wouldn’t interfere in their lives. But both their jobs required twenty-four-seven dedication, and clarity around that fact made him flinch. Could they have a happy marriage if they were both going in different directions with no time for one another?’”
That’s why Diamond in the French Blue is highly recommended for libraries seeking a strong series addition, readers who have enjoyed the previous exploits of Hope and Matt, and book clubs seeking a delicious combination of mystery and personal revelations that offer many thought-provoking points for discussion amid the action and investigative intrigue.
D. DONOVAN, SENIOR REVIEWER, MIDWEST BOOK REVIEW
“Hope fills in the blanks of what happened in the aftermath of a murder, tackling the underlying possibility of a curse affecting holders of the enchanting diamond also called French Blue, and the real meaning the blue stone holds for serious gem collectors.
“From questions of who stole the Hope Diamond to who is willing to commit murder to keep secrets hidden, Hope and Matt are again mired in another diamond-backed adventure that lands them in turmoil both in the world at large and in their own relationship.
“The foundations of Diamond in the French Blue lie in its predecessors, Diamond in the Desert and Diamond on the High Seas. Readers of all three mysteries will find the action and intrigue builds upon past events while creating an outstanding interplay of personal and professional challenges that lead each investigator to grow and learn, both separately and apart.
