Dr. Layanna James has mastered the art of healing broken hearts—except her own. At forty, she's one of the world's top cardiothoracic surgeons, but the sudden loss of her husband Angel has left her emotionally hollow and clinging to the routine of a life that no longer fits. Caleb Black knows grief intimately. A retired pro athlete, he once dreamed of traveling the world with his wife, Maria—until illness stole her from him far too soon. Now grounded in Winston Hills, he finds unexpected solace in the one woman who truly understands his pain: Layanna, his late best friend's wife. What begins as comfort between two grieving souls slowly simmers into something neither of them saw coming—desire, laughter, and a connection too strong to ignore. But love isn't easy when it's tangled in the past. As Layanna and Caleb navigate their growing feelings, they must also confront long-buried family secrets and the guilt that threatens to pull them apart. Enigma is a deeply emotional, slow-burning tale of healing, forbidden desire, and the courage it takes to choose happiness—no matter how complicated the path. With steamy passion, honest vulnerability, and flashes of unexpected humor, C.M. Barnes delivers a story where love dares to grow in the cracks of heartbreak. Narrated in duet style.
