Sophie Millar is the author of The Pull Beneath, the first book in the Tides Duet and the opening duet of the Agerstone series.

Drawn to stories filled with emotional tension, hidden secrets, and complex relationships, Sophie writes about the unseen forces that shape people’s lives. Her work explores the weight of the past, the families we find along the way, and the moments when trust and love begin to break down the walls we build to protect ourselves.

The fictional seaside town of Agerstone sits at the heart of her series — a place where lives intertwine, secrets surface, and every tide has the power to change everything.

When she isn’t writing, Sophie spends her time developing new stories set in Agerstone and connecting with readers who enjoy atmospheric romance and character-driven fiction.
