Emily St. John Mandel, bestselling author of Station Eleven and The Glass Hotel, is releasing a new novel, Sea of Tranquility, in April 2022.

Mandel wrote the book over the course of the pandemic, trapped in New York City for the entirety of 2020.

"This is the kind of book that happens when you're working in a soundscape of constant ambulance sirens," said Mandel in a press release.

According to the book's publisher, HarperCollins Canada, Sea of Tranquility "is a remarkable feat of storytelling that delves into themes that will be familiar to Mandel's many readers — time, art, love, wilderness, what makes the world real — and introduces readers to a remarkable cast of characters."

The novel traverses time, space and reality, introducing a wide range of characters living in British Columbia in 1912 and on the moon in 2401.

"There is, of course, a time traveller in it," said Mandel. "There is also an author living on a moon colony who visits Earth on a book tour."

Sea of Tranquility will be Mandel's sixth novel. Her most recent, The Glass Hotel, was a finalist for the Scotiabank Giller Prize and selected by President Barack Obama as a favourite book of 2020. The Glass Hotel revolves around a financial collapse, inspired by the Bernie Madoff fraud scandal, and the aftermath for both those who profited and those who were ruined.

Mandel's break-out novel was Station Eleven, a bestseller now being adapted for HBO. The 2014 book was a finalist for a National Book Award and the PEN/Faulkner Award and it won the 2015 Toronto Book Award. Station Eleven collected the stories of people wandering and surviving a world stripped down by a deadly pandemic.

Mandel is a dual American Canadian citizen and currently lives in New York.
