After ten years on the Amazon and surviving a shipwreck in which most of his work is lost, naturalist William Adamson, now lacking a home and means of his own, is taken in by his benefactor, Sir Harald Alabaster, who hires William to assist him with the writing of a book, as well as to tutor the younger of the children in residence on his estate. It's good fortune for William, who finds satisfaction in his work, as well as in making the acquaintance of one of Sir Harald's daughters, Eugenia, with whom he quickly becomes enamored. Eugenia, however, is a rather fragile flower, struggling with the inner demons of a dark secret born of unspeakable desires. Despite his best efforts, the shadows that plague Eugenia's soul remain. William, though, is determined to break through her darkness and bring her into the light, but some secrets are better left buried; and before it's over, William may discover more tragedy than he imagined.
