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?
FATAL INVITATION, the first crime thriller novel in the Detective Kylie Cassidy series by S.F. Baumgartner.
