GALLERY OF LOST SPECIES is about finding solace in unexpected places - in works of art, in people and in animals that the world has forgotten. Just as 13-year-old Edith Walker is about to leave childhood behind, she thinks she spots a unicorn high on a slope while hiking. Her daydreamer father Henry convinces her that what she's seen is real. Edith's sighting of the fabled creature - and her unfailing belief that the imaginary creature will eventually be found - sets in motion a series of events that impact the next decade of her life. .
