The Shadowed Son - Brenda Bailey

Gretchen Greenway-Jones spends her life trying to shield herself from pain. She married a kind man and poured love into raising two daughters, trying to outpace regret. Yet there was one man she abandoned- a secret she buried deep, and faraway from the world. Three decades later, her past crashes into her present. He has found her, and no matter how deeply she pleads for peace, he cannot let her go. He haunts her steps. Each place she goes, she feels his eyes, cold and relentless, digging up everything she tried to hide. His threats pierce her- he will tear her secret open for all to see, shattering the life she built to escape him. Driven by resentment, he is determined to make her pay for pushing him into darkness.

Who is this man? Her son.
