When a swan crashes through her window at the height of a winter storm, journalist Mitzi Fairweather decides to nurse the injured bird back to health. But at sunset, the swan becomes a woman.

This unexpected visitor is Odette, the swan princess — alone, adrift and in danger in 21st-century Britain, entirely dependent on the kindness of strangers. Bird by day, human by night, and with no way to go home, she remains convinced, to Mitzi’s distress, that only a man’s vow of eternal love can break her spell.

Mitzi is determined to help Odette, but as the two try to hide the improbable truth, their web of deception grows increasingly tangled. Can they find a way to save Odette before it’s too late?
