"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

Meet the Geezer Squad: How
a Book Club of Retired Sleuths Cracks the Ultimate Cold Case in SHADOWS OF THE
MISSING
by Lauren Carr
They look like your
friendly neighborhood book club—retired professionals sipping coffee, debating
plots, and swapping theories. But don’t let the cozy facade fool you. When a
real cold case lands on their table, the Geezer Squad turns into a force of nature.
In my newest novel SHADOWS
OF THE MISSING (out today!), that book club cover gets put to the test
like never before.
Chris Matheson, retired
FBI agent, never expected his wife Helen’s post to come knocking quite so
dramatically. But when her sister shows up with game-changing DNA results, the
disappearances of Helen’s parents—cold for decades—suddenly heat up. What really
happened to the young father who supposedly abandoned his young wife and
children? And did their overwhelmed mother simply wander away… or was something
far more sinister at play?
That’s when the full
Geezer Squad swings into action. This ragtag group of seasoned retirees (with a
combined century-plus of law enforcement and investigative experience) splits
into teams, leverages their unique skills, and dives deep into layers of deception,
conflicting witness accounts, and long-forgotten evidence. One dead body, three
missing people, and a trail that stretches back decades—it’s their most complex
and personal case yet.
I created the Geezer Squad
because I wanted to celebrate experience and wit over youthful bravado. These
aren’t superheroes; they’re real people with aches, quirks, sharp minds, and
the kind of wisdom only decades on the job can bring. One member might excel at
diving into the darkest corners of the internet or finding long forgotten
social media posts; another has a network of contacts that still opens doors.
Together, under the guise of discussing the latest thriller novel, they solve
cases that have stumped everyone else.
What makes SHADOWS OF
THE MISSING special is how deeply the case affects the team—especially
Chris and Helen. You’ll see new sides of familiar characters, laugh at their
banter and four-legged companions’ antics, and feel the emotional weight as
they chase justice for a family that’s waited far too long. One early reader
told me it had her on the edge of her seat, chuckling one minute and reaching
for tissues the next. That’s exactly the roller coaster I aim for!
Fans of the series will
spot a fun nod to the broader Lauren Carr universe (yes, there’s a Spencer
Inn reference that made me smile while writing). New readers? You can
absolutely jump in here—the book stands alone beautifully while introducing you
to a world of twisty mysteries, loyal friendships, and heartwarming (and
sometimes hilarious) moments.
If you enjoy cozy
mysteries with real bite—think intricate puzzles, clever sleuths who feel like
friends, and stories that mix suspense with genuine emotion—SHADOWS OF THE
MISSING is for you. It’s the perfect blend of police-procedural smarts and
heart that my readers have come to expect.
The book is live today!
Pick up SHADOWS OF THE MISSING and spend some quality time with the
Geezer Squad as they tackle shadows that have lingered far too long. (Read
FREE with Kindle Unlimited!)
Which character from a
book club or senior sleuth story is your favorite? Or if you’re new to the
series, tell me what draws you to cold case mysteries. I’d love to hear from
you in the comments.
Thank you for celebrating
release day with me!

My Review:
It seems it has been forever since I have had a Lauren Carr book in my hands. I was so excited to find out she was releasing a new addition to her A Chris Matheson Cold Case Mystery series called, Shadows of the Missing. I jumped at the opportunity to read it and was not disappointed. Once again, I was able to go on fun and entertaining adventure. It was great to catch up with Chris, Helen, and the Geezer Squad. This time the squad are on a mission to help Helen to solve the mystery of her parents' past. I was constantly left wondering of who did it and how it would end. I loved how the author throws in humor when you least expect it and makes me laugh out loud at times. Just perfect comedic timing woven in the mystery as the clues are uncovered. I loved every single page.
Shadows of the Missing is no doubt a five out of five star read. I highly recommend it for mystery and suspense lovers. I can not wait for another release by Lauren Carr soon and I hope there will be more to come from her A Chris Matheson Cold Case Mystery series. This one is most definitely not to be missed.
I received an advanced reader digital copy of Lauren Carr's Shadows of the Missing from the publisher, but was not required to write a positive review. This review is one hundred percent my own honest opinion.
