Two girls, two centuries apart. One never knowing the other. But when Andi finds Alexandrine’s diary, she recognizes something in her words and is moved to the point of obsession. There’s comfort and distraction for Andi in the journal’s antique pages - until, on a midnight journey through the catacombs of Paris, Alexandrine’s words transcend paper and time, and the past becomes suddenly, terrifyingly present.

Jo Montfort is beautiful and rich, and soon - like all the girls in her class - she’ll graduate from finishing school and be married off to a wealthy bachelor. Which is the last thing she wants. Jo dreams of becoming a writer - a newspaper reporter like the trailblazing Nellie Bly. Wild aspirations aside, Jo’s life seems perfect until tragedy strikes: Her father is found dead. Charles Montfort shot himself while cleaning his pistol.

Isabelle should be blissfully happy - she's about to win the handsome prince. Except Isabelle isn't the beautiful girl who lost the glass slipper and captured the prince's heart. She's the ugly stepsister who cut off her toes to fit into Cinderella's shoe...which is now filling with blood. Isabelle cut away pieces of herself in order to become pretty. Sweet. More like Cinderella. But that only made her mean, jealous, and hollow. Now she has a chance to alter her destiny and prove what ugly stepsisters have always known: it takes more than heartache to break a girl.

East London, 1888 - a city apart. A place of shadow and light where thieves, whores, and dreamers mingle, where children play in the cobbled streets by day and a killer stalks at night, where bright hopes meet the darkest truths. Here, by the whispering waters of the Thames, Fiona Finnegan, a worker in a tea factory, hopes to own a shop one day, together with her lifelong love, Joe Bristow, a costermonger's son. With nothing but their faith in each other to spur them on, Fiona and Joe struggle, save, and sacrifice to achieve their dreams.

Josephine Montfort is from one of New York's oldest, most respected and wealthiest families. Like most well-off girls of the Gilded Age, her future looks set - after a finishing-school education, she will be favourably married off to a handsome gentleman, after which she'll want for nothing. But Jo has other dreams and desires that make her long for a very different kind of future. She wants a more meaningful and exciting life: she wants to be an investigative journalist like her heroine, Nellie Bly.
