Sofia Bottom lives in Elysia, a small country forgotten by Europe. But inside its borders, the old myths of trees that come alive and faeries who live among their roots have given way to an explosion of the arts and the consolations of philosophy. From the clarinetists to the cabaret singers, no artist is as revered as Sofia’s brilliant mother, the writer Clara Bottom. How can 14-year-old Sofia ever hope to win her mother’s love? When the country’s greatest enemy invades, and the Capital is under threat, Clara turns to her daughter to smuggle her new manuscript to safety on the last train evacuating children from the city. But when the train draws to a suspicious halt in the middle of a forest, Sofia is forced to run for her life and loses her mother’s most prized possession. Frightened and alone in a country at war, Sofia must find a way to reclaim what she has lost.

Charismatic Marie Antoine is the daughter of the richest man in 19th-century Montreal. She has everything she wants, except for a best friend --- until clever, scheming Sadie Arnett moves to the neighborhood. Immediately united by their passion and intensity, Marie and Sadie attract and repel each other in ways that thrill them both. Their games soon become tinged with risk, even violence. Forced to separate by the adults around them, they spend years engaged in acts of alternating innocence and depravity. And when a singular event brings them back together, the dizzying effects will upend the city.

Two babies are abandoned in a Montreal orphanage in the winter of 1914. Before long, their talents emerge: Pierrot is a piano prodigy; Rose lights up even the dreariest room with her dancing and comedy. As they travel around the city performing clown routines, the children fall in love with each other and dream up a plan for the most extraordinary and seductive circus show the world has ever seen. Separated as teenagers, both descend into the city’s underworld, dabbling in sex, drugs and theft in order to survive. But when Rose and Pierrot finally reunite --- after years of searching and desperate poverty --- the possibilities of their childhood dreams are renewed, and they’ll go to extreme lengths to make them come true.
