Every Note by Heart by Linn Chapel

Vocal artist Vivienne Bennet makes every effort to stay out of the public eye. She works only nights as she carefully guards the secret of her true nature. Peter Newman has his own struggles. Between his teetering career as a videographer and his troubles in the spirit world, he has his hands full, and he wants nothing to do with the temperamental singer.
Unortunately, they’re both strong-willed and hot-headed. In fact, there couldn’t be two people less likely to get along.

Vivienne expects her bleak life to improve when she enters a very unusual community. With her predatory instincts held in check, she professes her vows and enters The Sisterhood during a midnight solstice ritual.
The Sisterhood:a secretive band of women who all have a reason for hating men. They’ve even added a new vow to undermine the efforts of men whenever possible. And only the Leader and the other members of the Council are aware that Vivienne’s not human.

But when the famous singer with the stellar voice finds herself under urgent pressure to film her first promo video, disaster is looming. She soon learns that the fresh insights of her new coach hold the key to success for the whole project.
Unfortunately, Peter Newman is just as strong-minded as her. And on top of that, he’s a man whose looks are causing all the other women at the studio to make fools of themselves.
But Peter is her only hope, and so Vivienne finds herself relying upon him despite her vows with The Sisterhood.
When Peter encounters his own chilling problems, Vivienne stumbles upon the strange and perilous hidden realm of spirits where she barely escapes the predatory demons that lurk in that otherworld.

But all too soon, Peter discovers he needs the help of the beautiful singer – despite his own personal code.
