Cruel Grace by Olivia Jaymes

The night the lights went out in Seattle…

During a blackout, Eli Hammond finally talks to his extremely attractive neighbor, Charlotte “Charlie” Baker, from across the hall. He’s seen her around, but they’ve never moved past the nodding and smiling stage. Tonight, he’s offered her part of his dinner and some company in the candlelight.
They talk for hours, but when Charlie finds out Eli used to be a sheriff, she’s in a big hurry to leave. She’s had enough of cops to last a lifetime. It’s too bad, though. She really liked him. But Charlie has secrets, and she’d like to keep them that way. She’s managed to build a life for herself. She doesn’t want to look back.
But what was dead and buried is bound to rise again. Soon Eli finds himself and Charlie tangled in her dark past. They both want to finally find the truth, but someone out there is standing in the way.
And that person is a killer. Will Eli and Charlie be their next victim?
