It’s your eighteenth birthday and one of your parents must die. You are the one who decides. Who do you pick?

In a dying world, the Offset ceremony has been introduced to counteract and discourage procreation. It is a rule that is simultaneously accepted, celebrated and abhorred. But in this world, survival demands sacrifice, so for every birth, there must be a death.

Professor Jac Boltanski is leading Project Salix, a ground-breaking new mission to save the world by replanting radioactive Greenland with genetically modified willow trees. But things aren’t working out and there are discrepancies in the data. Has someone intervened to sabotage her life’s work? Meanwhile, her daughter Miri, an anti-natalist, has run away from home. Days before their Offset ceremony where one of her mothers must be sentenced to death, she is brought back against her will following a run-in with the law. Which parent will Miri pick to die: the one she loves, or the one she hates who is working to save the world?

Praise for The Offset

“A short, sharp shock of a book […] undeniably a powerfully told debut” – SFX Magazine

“These co-writers have produced a vision of a blighted world where everyone has to make sacrifices for the greater good, personal happiness being the first thing to go.” – The Financial Times, listed as one of the best science fiction books of 2021

“Smart, compelling and absolutely of the moment. A truly elegant debut.” – Luke Jennings, author of the Killing Eve series

The Offset is spare, elegant, and thought-provoking as the best classic science fiction. Calder Szewczak is a name to watch.” – Daniel Abraham, co-author of The Expanse series

The Offset could do for environmentalism what Nineteen Eighty-Four did for socialism and Brave New World did for eugenics.” – Ken MacLeod, Prometheus and BSFA Award-winning author of The Corporation Wars series

“Thrilling, terrifying and beautifully crafted, The Offset is the perfect science-fiction novel for our times. I devoured it.” – Angela Saini, author of Inferior

The Offset was a dark and fascinating read – a twisted reversal of The Handmaid’s Tale set in a ravaged dystopia, simmering with menace and tension. Bleak, haunting and intriguing.” – Jennifer Saint, The Sunday Times bestselling author of Ariadne

“Calder Szewczak’s The Offset may be a literary first in giving central place to anti-natalism” – David Benatar, author of Better Never to Have Been

The Offset is a prophetic, urgent, gripping read that throws into question what saving the world really means. A tender warning of a book, lest our efforts become as futile as our tragedies.” – Natalia Theodoridou, World Fantasy Award Winner and Nebula Finalist

“An honest, terrifying and sincere look into our future.” – Keren Landsman, Geffen Award-winning author of The Heart of the Circle

“A chilling evocation of a possible future.” – Susannah Wise, acclaimed actress and author of This Fragile Earth

The Offset is a bleak but thoughtful dystopian sci-fi. It asks questions about where we are & where we are going through intricate world building and a compelling story. Very entertaining, compulsive & thought-provoking.” – Kate Sawyer, author of The Stranding

“Finished this and now I’m slightly broken. If, like me, every so often you just want a bit of beautiful, brutal dystopia this is the one for you! A complex world filled with complex characters that draw the reader in. This is a beautifully written, brutal piece of dystopian fiction that does not shy away from the issues we must face today.” – Elizabeth Lee, author of Cunning Women

The Offset crushed me. This is an expertly – and starkly – written, well-drawn eco-dystopian novel about the ultimate measure of austerity taken in order to save the planet. There’s so much that was done well here: the world, the science, the societal conflict – but to get into the (possibly carnivorous) weeds would distract from soul of this book. It is a bare-knuckle punch to the heart. Calder Szewczak made me suffer – brilliantly.” – Chris Panatier, author of The Phlebotomist
