Betsy Green has loved George Walker for as long as she can remember.

He is her best friend's older brother—the boy who once pulled her from the river, the man who returned from Manchester determined to transform his family's mill and rise far beyond their small northern town.

But George Walker does not see Betsy.

While she admires him from the shadows, George's ambitions push the mill harder, faster, and more dangerously than ever before. When disaster strikes—first a deadly explosion, then an accident that shatters Betsy's family—the devotion she once held so fiercely begins to fracture.

As unrest grows in the town and grief tears their lives apart, Betsy must finally face a painful truth: loving George Walker may cost her everything.

And George, blinded by ambition for too long, may only realise what she means to him when she is already walking away.
