my review
Shadows of the Missing offers an engaging, well-developed mystery. This novel pulled me in immediately. There is a mix of suspense and humor, strong characters, and a mystery that unfolds at just the right speed. Lauren Carr does a great job layering clues throughout the story so the investigation feels engaging without becoming overly complicated. Twists and turns always add something to the storyline and are presented so that they seem reasonable and not too coincidental or contrived. Every chapter seemed to reveal something new, and the mystery developed in a way that kept me guessing while still feeling believable and well-developed.
Expect characters to love. One of the biggest strengths of this series continues to be the characters, especially Chris Matheson. He has the kind of personality that makes him easy to root for, and his interactions with those around him add a lot of charm and humor to the story. The dialogue feels natural, and the relationships between the characters add depth without taking attention away from the mystery itself. Lauren Carr's writing style makes these characters feel familiar and real, which is part of why returning to this series is always so enjoyable for me. I love the humor in the dialogue--and always look forward to any animal antics in her books.
Would I recommend Shadows of the Missing? I would absolutely recommend Shadows of the Missing (as well as the entire series) to readers who enjoy mysteries with engaging characters, smart investigation work, and a touch of humor woven into the suspense. Fans of the previous books in the series will definitely want to pick this one up to catch up with the characters' lives. While I think reading the books in order is best for this series because the characters' relationships and past adventures add so much to the pages--it also works well for anyone looking for a stand alone mystery that’s entertaining, fast-moving, and easy to get invested in. Lauren Carr continues to deliver the kind of storytelling that keeps me coming back for more, and this was another thoroughly enjoyable read.

"Lauren spins an amazing web of lies, murder and love that will have you on the edge of your seat...I love the way Lauren spun this novel - I could not put the book down! I had to know what happened to Sandy and her unborn child and how this disappearance was tied into a string of other murders. I never saw the end coming but it was perfect and suited the novel. A definite must read novel!" 5-Star Review by Carla at Working Mommy Journal

"Filled with twists and turns, Winter Frost reads perfectly well as a stand-alone, although it is part of a series. The author creates tension and suspense throughout by keeping the reader guessing; she keeps readers engaged with well fleshed out characters and a dash of humor. Sterling, the retired German Shepherd police dog turned card shark, is a new favorite. As the story flows, the truth unfolds, layer by layer, leading to a satisfying conclusion.
"Winter Frost was an entertaining, at times humorous read with suspense, some surprises, and even cute animals in the mix." Review of Winter Frost by The iRead Review

"Too many twists and turns to easily share about this book. Nevertheless, Carr has pulled off another "hit" that kept me reading in one setting until the clues were so well together that the villain fell into our laps...or Chris's, LOL Carr has put a lot into the book beyond the mysteries this time...Characters enjoyed chocotinis, visited book stores...and even blundered into getting engaged (the ring had been purchased 4 months ago)... But, for me, a special thank you for the political spoof at a time when politics at the national level is devastating, gave me a laugh and lightened the load of it all!" - Review by Glenda Bixler, Book Reader's Heaven
