The Sound of Secrets by Jay Crownover

Some secrets are silent.
It began with a contract, with Channing Harvey being forced into marriage by the world’s grumpiest billionaire. She hated every moment of her marriage to Win Halliday… until she didn’t. It was hard to resist when he proved he valued her more than his massive fortune. Channing is having a hard time picturing her life without him, and if Win finds that out, he won’t rest until he has all of her. Deep, dark secrets included.

Some secrets scream.
Win Halliday is so close to having everything he’s ever secretly wanted. He’s ready to do battle with Channing’s demons, no matter what they are. Or who they might be. Someone from Channing’s past wants to use her, and they’ll go to desperate lengths to get what they want, including targeting an innocent teenager. But whatever lengths they go to, Win will go farther. He finally has the family he’s dreamed of, and he will protect them at all costs.
