About the Book
Book: Fatal Invitation
Author: S.F. Baumgartner
Genre: Crime Thriller

Vanished women. A rising body count. A detective who won’t quit.
Detective Kylie “KC” Cassidy thought Major Crimes would be her big break. Instead, she’s chasing the brutal murders of young women—and the trail keeps circling back to Assistant State Attorney Gavin Watkins and his elusive ally, Kozlov.
Each lead vanishes before her eyes, every step forward dragging her deeper into danger. And when Kozlov’s men come after her, KC must rely on her instincts, and on the few people she can trust, to survive long enough to expose the truth.
But when KC gets too close to the truth, she becomes the target. Will KC survive the trap and bring down the predators or become their next victim?
If you like the relentless pursuit of justice in Michael Connelly’s Harry Bosch series, the sharp investigative instincts of Lisa Gardner’s D.D. Warren, then you’ll be captivated by Fatal Invitation, a gripping, fast-paced crime thriller.

About the Author

S.F. Baumgartnercrafts fast-paced Christian suspense thrillers, weaving tales of complex characters, secretive operatives, and relentless agents. Her gripping storytelling has earned acclaim, with Living Secrets and Forgotten Secret—Books 1 & 2 of her Mirror Estate series—named Top Picks in the thriller & suspense categories, respectively, at Killer Nashville, and Tangled Secrets—Book 3 of Mirror Estateseries—won couple of awards in the Christian Indie Awards and the Incipere Awards.

A New Adventure Begins: Introducing the Detective Kylie Cassidy Series
I’m thrilled to announce that Fatal Invitation, the first full-length novel in the Detective Kylie Cassidy series, is here!
If you’re new to Detective Kylie “KC” Cassidy, I recommend starting with Christmas Murders to get acquainted with this compelling character. And here’s a treat: there’s a free story called Orlando Prime – Origins available under the Freebie tab on my website at sfbaumgartner.com. This story introduces you to the elite crime-fighting unit and the team members who work alongside KC. Both KC and Orlando Prime take center stage in Fatal Invitation.
Writing this book has been an absolute blast! Unlike my Mirror Estate series, the Detective Kylie Cassidy series features self-contained stories in each book—think of it like your favorite TV crime drama where each episode (or book) solves a complete case. While there may occasionally be an overarching storyline, you can jump in at any point and enjoy the mystery. And as always, my books are clean reads.
Since this is a spin-off of the Mirror Estate series, longtime readers will enjoy spotting familiar faces. A few beloved characters get mentioned, and some may even guest-star in future books!
I truly hope you’ll fall in love with this new series as much as I’ve loved creating it.
Happy Reading!
My Impressions
“KC felt the familiar chill that came with recognizing a pattern. A beautiful influencer. A too-good-to-be-true opportunity. A young woman who trusted the wrong person.”
Whew! I escaped alive out of that crime thriller! S.F. Baumgartner writes in such a compelling way, I thought I was present in the scenes of Fatal Invitation. This series is a spin-off of the Mirror Estates series. Each book in the series can be a standalone. Kylie “KC” Cassidy is a small town detective who has just moved up to the Orlando Police Department. Still, the very first murder victim she investigates is one from her small town where she used to live with her Aunt Mae.
When a second victim with a similar MO is found shortly after, KC and her partner fight to keep jurisdiction from turning over to Orlando Prime, the city’s elite crime fighting organization. One aspect of the book is following KC and her new partner, Spaulding, to see if they can learn to work together and trust each other. After so long working by herself, can KC adjust to not only having a partner, but sharing her case with a whole nother unit?
Another is getting an overview of the Orlando Prime team, headed by Commander Frank Travers and his gang that is almost like family. I enjoyed meeting all of these individuals, and getting a feel for their place in crime solving. Jack has to be the comic relief of the team, in a sense. He is so very intelligent, but can he ever bird-walk. I could feel the whole team groaning whenever it was time for him to report in!
KC and the Orlando Prime team first believe they are tracking a serial killer. But what they eventually uncover is something more planned, more pervasive, and more deeply rooted than they could have imagined. Do they have the skills and resources to expose something so sinister before it takes them, especially KC, out?
Be ready for lots of characters, fast action, nail-biting tension, and a few twists. I will be looking forward to reading the rest of this clean, crime fiction series!
I received a copy of the book from Celebrate Lit. I also bought my own ebook. No positive review was required, and all opinions are my own.
Notable Quotables:
“And men under pressure do two things.” Eli’s voice lowered. “They break, or they double down.”
“He’d thrown away his medical license, his marriage, his self-respect. But maybe, just maybe, he could throw away his fear too.”
“But some of the most dangerous predators operated in plain sight, hiding behind credentials and public trust.”
