Wow! Barbara Freethy has once again delivered an incredible romantic thriller with Critical Doubt. Each book in Barbara Freethy's Off the Grid: FBI series gets better and better, and I think that Critical Doubt is my favorite book in the series. I absolutely loved Critical Doubt, the seventh book in her Off the Grid: FBI series. Critical Doubt had me guessing throughout the story what was really going with the former Army Rangers and the other thrilling events. I could not put it down. I loved every page. I really enjoy how the book is told from the perspective of the main characters. I love getting the insight and feelings from the different characters. Barbara Freethy has once again proven that she is a master storyteller. Critical Doubt is the story of Ryker Stone, former Army Ranger and Chesapeake Bay fishing charters boat owner and Savannah Kane, an undercover FBI agent, former beauty queen, former Army Intelligence officer and daughter of Army Colonel Henry Kane. Ryker and Savannah meet again when they both head to Dobbs, Georgia for the funeral of Paul Hawkins, husband of Savannah’s childhood best friend, Abby and Ryker’s Army Ranger team member. Savannah and Ryker had originally met five years ago in a bar in a war zone and had a one-night stand with no names. Savannah discovered Ryker’s identity several years ago, when see saw a picture of Paul’s Army Ranger team at Abby’s home. After Paul’s funeral, another team member is involved in an accident, Ryker jumps in the river to save him. After multiple attempts on their lives, the relationship between Ryker and Savannah changes. Neither is sure if their relationship is just fueled by the adrenaline from the chase. I loved the relationship between Ryker and Savannah. Savannah reaches out to her team for help when things got complicated. I love how Savannah helps Ryker with the debilitating ringing bells that he suffers with. Eventually all clues lead them to what really is going on with Ryker’s former Army Ranger team member, I did not see that happening. That was such a surprise twist for me. I really enjoy the poignant and bittersweet moments, the plot twists and the surprises that I have come to love and expect in Barbara Freethy's books and Critical Doubt did not disappoint. One of my favorite parts of the story are the poignant moments that Savannah has during conversations with her father, who she has been estranged with since the death of her mother when she was thirteen years old. I loved all the secrets that Ryker and Savannah shared with one another. I love that Ryker realizes Savannah’s vulnerabilities. I love that Ryker agrees to relocate to be closer to Savannah. I love that all the characters from the previous books were included in Critical Doubt. It felt like a family reunion and I loved catching up with the other characters from the series. I love how all Barbara Freethy's epilogues, wrap up the ending of the story and are always my favorite part of her books. I love how all the loose ends got tied up. I love all the characters and the way Barbara describes the locations in and around Dobbs, Georgia, Washington, DC, Baltimore and Los Angeles. It was really an incredible story and I loved every page.
