"Debut author Jordan Stratford imagines an alternate 1826, where Ada Lovelace (the world's first computer programmer) and Mary Shelley (author of Frankenstein) meet as girls and form a secret detective agency! Lady Ada Byron, age eleven, is a genius. Isolated, awkward and a bit rude-but a genius. Mary Godwin, age fourteen, is a romantic. Adventurous, astute, and kind, Mary is to become Ada's first true friend. And together, the girls conspire to form the Wollstonecraft Detective Agency-a secret constabulary for the apprehension of clever criminals. Their first case involves a stolen heirloom, a false confession, and an array of fishy suspects. But it's no match for the deductive powers and bold hearts of Ada and Mary. Filled with witty banter, daring balloon chases, and two unforgettable heroines, The Case of the Missing Moonstone marks the debut of a dynamic new series for science lovers and history buffs everywhere!
