He was the boy they told her never existed.

Now he's the man who might shatter everything.

A new heart-pounding, suspenseful, and supremely romantic novel from New York Times bestseller Mia Sheridan.

Autumn Sterling has spent her life haunted by dreams of a boy with silver hair and moonlight eyes—a presence so vivid, she swore he was real. Everyone said he was a figment of her imagination, a side effect of a twisted medical experiment that turned children into ghosts of themselves, but Autumn never believed them.

She felt him. Touched him. Loved him. Her moonlight monster.

Now a nurse trying to live a life of purpose beyond her pain, Autumn's world implodes when she sees that face—his face—on a crowded street. Sam is no ghost. He's flesh and blood. And he's been running from horrors far worse than anything Autumn has ever dreamed of.

Reuniting unlocks a flood of memories and secrets. Together, Autumn and Sam begin unraveling a hidden legacy of cruelty, cover-ups, and corruption. As the danger mounts and enemies close in, it's not just their lives on the line, but the truth of who they were, who they are, and who they could become.

In the shadows of their pasts, can two broken souls find a way to heal...and hold on to each other?
