'Audaciously tackles life's most formative experiences: love and loss' RUMAAN ALAM, New York Times bestselling author of Leave the World Behind

'Like walking down a hall of mirrors . . . Lightbreakers made me see things anew' LING MA, prize-winning author of Severance

'You will love this genre-busting book . . . A cross of literary fiction and sci-fi, it's also a beautiful meditation of grief, time, and love' SAMIN NOSTRAT, bestselling author of Salt Fat Acid Heat

Maya, an artist, and Noah, a quantum physicist, are happily married. But beneath the surface of their wedded bliss is a third rail: Serena, the lost child that Noah had with his ex-wife.

When Noah gets a call from an eccentric billionaire asking him to participate in a clandestine project aiming to unravel the secrets of time and consciousness, the couple agrees to relocate to the Janus Lab, deep in the desert, and Noah finds himself drawn into a dangerous kind of time travel that could result in seeing Serena again.

But Janus lab is not what it seems, and soon Noah and Maya are drawn into its dangerous web, where they must grapple with their pasts and plumb the depths of human connection to find their way back to one another.

'Compassionate and prismatic . . . my favourite kind of novel' CHLOE BENJAMIN, New York Times bestselling author of The Immortalists

'Both gripping and deeply felt, as breath-taking as it is mind-bending . . . it exists in a category all its own' RACHEL KHONG, New York Times bestselling author of Real Americans

Industry Reviews

Audaciously tackles life's most formative experiences: love and loss. Lightbreakers explores how people use both science and art to understand the universe-offering us its own insights into what it is to be human - Rumaan Alam, New York Times bestselling author of Entitlement and Leave the World Behind

Exists in a category all its own: a novel about grief, ambition, and love that is somehow both gripping and deeply felt, as breath-taking as it is mind-bending. Aja Gabel's prose is like music, vivid with wisdom, curiosity, and emotion. This is a book that tenderly examines the limits of our understanding-about the universe and each other-and the strangeness of living in time - Rachel Khong, New York Times bestselling author of Real Americans

Lightbreakers is compassionate and prismatic, an intellectual adventure as well as a deeply human meditation on memory, family, and reinvention. To what extent-and at what cost-can the past sustain us? How can we step into the future without abandoning our previous selves? Aja Gabel's second novel is my favorite kind: soulful science fiction that speaks to the mind as well as the heart - Chloe Benjamin, New York Times bestselling author of The Immortalists
