Joanne Owen was born in Pembrokeshire, Wales, and read Social and Political Sciences with Archaeology and Anthropology at St. John's College, Cambridge. Now living in North London, Joanne has published two previous Young Adult novels. Steeped in the atmosphere of nineteenth-century Prague, Puppet Master blends the magic of marionette theatre with Czech folklore and legends. Described by The Guardian as "timeless," Puppet Master was longlisted for the Carnegie Medal and Branford Boase award and has been translated into several languages. Her second novel, The Alchemist and the Angels, is a fantastical historical epic set in sixteenth-century Prague, among the plague-ridden ghettos and decadent court of mad Emperor Rudolf. It was described by School Librarian as "an imaginative tour de force." Her third novel, the wonderful gothic tale Circus of the Unseen, was published by Hot Key in 2014. The brilliantly magical Martha Mayhem is her newest series. Follow Joanne on Facebook at www.facebook.com/JoanneOwenBooks or on Twitter: @JoanneOwen.
