Beautiful, daring and outstanding Avery dreams of becoming a member of the Royal Astronomical Society – and the only path she can join the all-male society is normally to disguise herself being a boy. After helping Giles, Lord Strand, get away a devastating engagement she is certain he will assist in her daring masquerade. No lady would ever produce such a preposterous system, no gentleman would accept . but luckily for Avery, Giles is no gentleman. A bargain is struck between your stargazing adventuress and society’s most advanced lord. He’ll sponsor her as his prodigy and she’ll cover for him as he hunts London’s darkest warrens for the lacking colleague from his shadowy previous. But over and over Giles finds his quest compromised by his fierce and unwise attraction towards the wonderful girl who, though no lady, may well be the main one dame to finally unlock the secrets of his heart.
