A memory-impaired time traveller attempts to correct a tragic mistake he made in 1977 when, panicked, he abandoned his brother on a frozen lake in Baltimore. Decades later, in 2011, a novelist researching at the Centre for Time in Sydney becomes romantically involved with a philosopher from New Zealand. A writer at a lake retreat in New Zealand in 2019 obsesses over the disintegration of his marriage following another tragedy. Are they separate stories, or are they one? Is the time traveller actually travelling? Can the past be changed? As the answers to these questions slowly emerge, the lives become entangled in a tale of love, desperation and physics.

“This is a book that makes you slow down your reading because you don’t want the experience to end. That calls to you when you’re going about your day. That makes you nudge your partner to say, Listen to this. Entanglement is erudite, romantic, deeply moving. I reached the end and turned straight back to page one, entangled.” —Gigi Fenster

“A novel full of two things I can’t stand in fiction—audaciously long sentences and a protagonist who’s a writer —and yet I freaking love this book! Walpert has not only the ear of a poet, but also the ruthlessness of a novelist skilled at unpicking human relationships. Trust me, this story will unfold like a set of dominoes arranged in the shape of your heart.”
—Madison Hamill, author of Specimen
