The Extraordinary Adventures of the Athena Club Series

Mary Jekyll, alone and penniless following her parents' deaths, is curious about the secrets of her father's mysterious past. One clue in particular hints that Edward Hyde, her father's former friend and a murderer, may be nearby, and there is a reward for information leading to his capture...a reward that would solve all of her immediate financial woes. But her hunt leads her to Hyde's daughter, Diana, a feral child left to be raised by nuns.

Mary Jekyll’s life has been peaceful since she helped Sherlock Holmes and Dr. Watson solve the Whitechapel Murders. Beatrice Rappaccini, Catherine Moreau, Justine Frankenstein, and Mary’s sister Diana Hyde have settled into the Jekyll household in London, and although they sometimes quarrel, they can always rely on Mrs. Poole. But when Mary receives a telegram that Lucinda Van Helsing has been kidnapped, the Athena Club must travel to the Austro-Hungarian Empire to rescue yet another young woman who has been subjected to horrific experimentation.

Life’s always an adventure for the Athena Club...especially when one of their own has been kidnapped! After their thrilling European escapades rescuing Lucina van Helsing, Mary Jekyll, and her friends return home to discover that their friend and kitchen maid Alice has vanished - and so has their friend and employer Sherlock Holmes! As they race to find Alice and bring her home safely, they discover that Alice and Sherlock’s kidnapping are only one small part of a plot that threatens Queen Victoria, and the very future of the British Empire.
