When Heather Jane Bell is diagnosed with alopecia and her hair starts falling out in clumps, she wants nothing more than to escape her home in London and disappear off the face of the earth. Heather gets her wish when her concerned parents send her to stay with her great-aunt in West Yorkshire.

But shortly after she arrives, she becomes lost on the moors and is swept through the mist back to the year 1833. There she encounters fifteen-year-old Emily Bronte and is given refuge in the Bronte Parsonage.

Unaware of her host family's genius and future fame, Heather struggles to cope with alopecia amongst strangers in a world completely foreign to her. While Heather finds comfort and strength in her growing friendship with Emily and in the embrace of the close-knit Bronte family, her emotions are stretched to the limit when she falls for Emily's brilliant but troubled brother, Branwell. Will Heather return to the comforts and conveniences of the twenty-first century? Or will she choose love and remain in the harsh world of nineteenth-century Haworth?
