Bluebell's Stalker

The hairs on the back of her neck insist someone’s been following Bluebell home from work. She feels it at the grocery store, too. Unless it’s just nerves from living alone since her father’s recent death. Finding a squatter’s nest in the back of the warehouse doesn’t help.
And then there’s the new guy who recently started volunteering at work. Why does electricity shoot through her when they touch? She can feel it the moment he walks into the room with her. Could he be her stalker? Is it the squatter? Why would anyone be interested in following her around, anyway? It’s not like she’s someone rich or famous.
Who is Bluebell’s Stalker…and why is he after her?
