Like many artists, Calliope dreams of painting beautiful works of art that stir the soul. Unfortunately, the only paintings of hers that sell are the ones that kill people.

She's compelled to paint by a dark presence she doesn’t understand and can't control. No matter what it takes, she must find a way to resist the urge to submit to the power inside her, because once she dips her brush in red, someone is about to die bloody.

When Knox sets eyes on the most beautiful woman he's ever seen, he's drawn to her in a way he can't explain. Too bad she's dating his brother's murderer.

Certain that Calliope will be the killer's next victim, Knox makes it his mission to keep her safe. He soon realizes there's more to the talented artist than meets the eye. She's a vessel for slivers of ancient, powerful souls, and she doesn’t even know it. Those shards have an agenda of their own, and they will use her—or destroy her—to get what they want.

As she and Knox hunt for a killer, they learn that their two fates are inextricably bound, and if they can't find a way to control the power Calliope possesses, then the next gruesome murder she paints may be her own.
