Loner's Scheme by Karen D. Bradley

Meisha Blake's attempt to prove the innocence of someone close to her after his death made her a target of a dangerous group. She moved Onyx Cove, Illinois, to reset her life and keep her family safe. Working for Harvest Power is supposed to give her time to figure out a way to put an end to the threat. Then things begin to happen that make her question whether she's put herself in a more dangerous situation.

Brett is working as an IT technician at Harvest Power on the trail of an organization scamming companies out of millions and leaving unsuspecting employees to take the fall. A victim's father hired him to obtain evidence that would put the actual wrongdoer behind bars, but his efforts to keep the lovely loner Meisha out of trouble may cost him his opportunity to bring them down.

Will Brett's attraction to Meisha cause him to sacrifice the lives of the other employees for hers? Will Meisha's secrets be the death of Brett?
