Georgiana Linfield is a lady biologist who is determined to travel the world. Upon arriving in London for the Season, she decides the best way to fulfil her dreams is to find an amenable husband to indulge her every whim. Refusing to give up her interest in natural history for a dull domestic life, she sets out to forge a different path for herself. When her father's elderly cousin asks her to set his natural history collection in order, she accepts his request with joy. However, the task brings her into almost daily contact with his godson, Sir Giles Tavistock, a renowned entomologist, who regards her with some suspicion. When Sir Giles discovers her skills as a scientific illustrator, he asks her to sketch his South American butterfly collection, and they forge an uneasy truce. Their tenuous connection is shattered, however, when Sir Giles believes a rumour casting Georgiana in a far from flattering light. Vowing to have nothing more to do with him, she keeps him at a distance. But when the baronet's butterflies attract unwanted attention, a series of events unravel that make Georgiana wonder if the famous collector might have done the impossible and captured her heart.
