The Wife Before by Shanora Williams

Samira Wilder has never had it easy, and when her latest lousy job goes south, things only promise to get harder. Until she unexpectedly meets a man who will change her life forever. Renowned pro golfer Roland Graham is wealthy, handsome, and caring, and Samira is dazzled. Best of all, he seems to understand her better than anyone ever has. And though their relationship moves a bit fast, when Roland proposes, Samira accepts. She even agrees to relocate to his secluded Colorado mansion. After all, there’s nothing to keep her in Miami, and the mansion clearly makes him happy. Soon, they are married amid a media firestorm, and Samira can't wait to make a fresh start—as the second Mrs. Graham . . .

Samira settles into the mansion, blissfully happy—until she discovers long-hidden journals belonging to Roland’s late wife, Melanie, who died in a tragic accident. With each dusty page, Samira comes to realize that perhaps it was no accident at all—that perhaps her perfect husband is not as perfect as she thought. Even as her trust in Roland begins to dwindle and a shadow falls over her marriage and she begins to fear for her own life, Samira is determined to uncover the truth of Melanie’s troubled last days. But even good wives should know that the truth is not always what it seems . . .
