Before Eve is conceived, her mother goes to the circus to watch the heart-stopping main attraction: a lion. When Eve is born, the story goes, she didn’t cry – she meowed and licked her paws. When Abel is pulled from the stinking Thames, the mudlarks are sure he is dead but as they divvy up the contents of his pockets, his eyes crack open. Cast out by Victorian society, Eve and Abel soar to fame as The Lion Faced Girl and The Flayed Man, the star performers in Professor Josiah Arroner’s Palace of Curiosities. And there begins a journey that will entwine their fates forever.
