MURDER IN DARK WATERS
by Carla Cassidy

Angelique Santori has vowed that she’ll find her mother’s murderer. When Chief of Police Daniel LeCroix asks her to let the police handle things, they reach an agreement: She’ll go back to her life if he gives her updates on the case. But Daniel isn’t the only one who wants Angelique to stop digging… After she barely escapes a vicious attack, he’s even more insistent that she stay out of his case. She can’t deny that she’s attracted to him, but once her own life is on the line, she asks herself if she’s finally found a man she can trust.

EYEWITNESS IN DANGER
by Nicole Helm

Sheriff’s Deputy Royal Campbell knows he’s been assigned to quiet little Hope Town because he’s the rookie. Things get interesting when Franny Perkins witnesses a kidnapping and the FBI takes over Royal’s investigation. The Sheriff wants Royal to stay close to Franny for her safety and because of Royal’s experience with the feds—even though that experience was on the other side of the law. Staying close to Franny gets more complicated once it’s clear that she’s in danger. And after she and Royal share one reckless kiss… 

EXPLOSION AT THE MARINA
by R. Barri Flowers

When she witnesses her brother’s boat explode, Raquelle Jernigan fears the worst. Relief that he escaped a bomb meant for him turns to terror when she learns he was her ex-husband’s confidential informant. FBI Special Agent Landon Briscoe regrets every moment of the four years he and Raquelle have been apart. Now he must put aside past heartache to find the missing CI who was helping infiltrate an art forgery ring. With danger lurking everywhere, can Landon catch a killer and protect the woman he still loves?
