Dark Horizon follows Ethan Cross, a determined and ambitious man who rises from the gritty underbelly of a law firm to become the governor of his state. Forty-two days into his term, Ethan revels in a landslide 68% approval rating after toppling the corrupt empire of Senator Langston with damning evidence. However, his victory is short-lived as a new threat emerges Thomas Caldwell, a powerful land developer with shadowy investors, pushes a suspicious oil drilling deal that could control vital water reserves. As Ethan digs deeper, he uncovers hints of a mysterious force known as The Umbra—ancient, hidden power brokers who manipulate events from the shadows. When Caldwell is murdered in jail under suspicious circumstances, Ethan’s pursuit intensifies, leading him to an abandoned quarry that may hold the key to The Umbra’s secrets. With his trusted allies—chief of staff Robert Hale, assistant Sarah Whitmore, detective Henry Hightower, and a team forged in battle—Ethan confronts a conspiracy spanning decades, threatening not just his governorship but the very fabric of the state he swore to protect. A gripping political thriller, the novel blends ambition, betrayal, and a relentless quest for truth against a backdrop of escalating danger.
