Dark Horse by London Miller

First came love.
Then came hate.
And now? Now, there was only war.
When he crossed paths with Karina Ashworth all those years ago, Uilleam Runehart didn’t expect his world to get turned upside down—but he also hadn’t known what it meant to love someone as he loved her.
But greed can corrupt so easily, and what he possessed, he lost just as quickly.
Even knocked off his feet, however, Uilleam isn’t one to back down without a fight, no matter how impossible the odds.
There’s a reason they call him the Kingmaker, and now it’s time to show everyone what that title really means.
