The Silence of Monsters by Jay Crownover

Win Halliday lives an extraordinary life
When he moves, the rest of the world moves with him. As the heir to the Halliday name and fortune, Win’s entire life has been carefully orchestrated from the moment he came into the world. He’s never been allowed to aspire for anything outside that plan, including love. After the tragedy that followed his younger brother chasing his foolish heart, the Halliday Matriarch insists on picking a bride that’s up to her outrageously high standards. Unfortunately, for all the eager bachelorettes, the only woman Win would ever consider marrying isn’t found anywhere on his mother’s list.

He’s got his eye on the exceptionally ordinary, Channing Harvey.
There’s so much history and hatred between the two of them, that a happily ever after is impossible. Win doesn’t need forever, he just needs to get his tyrannical mother off his back.
Channing’s not interested in his millions or his ridiculous contract marriage offer, but she’s about to learn that Win Halliday is relentless. This is the first decision Win has made with only himself in mind, and nothing’s going to stop him from getting what he wants.

They’re getting married, and God help whoever gets in Win’s way — including his very reluctant bride-to-be.
The only monsters found within this novel are of the human variety. But they’re still scary!
