Winner of the 2021 CBCA Book of the Year for Older Readers and the NSW Premiers Literary Awards Ethel Turner Award for Young Adult Fiction. Told from the points of view of two unreliable narrators, this twisty YA novel is part mystery, part thriller, part dystopian drama, suitable for readers 14+.

The blurb says:

Identical twin sisters Summer and Winter live alone on a remote island, sheltered from a destroyed world. They survive on rations stockpiled by their father and spend their days deep in their mother’s collection of classic literature—until a mysterious stranger upends their carefully constructed reality.

At first, Edward is a welcome distraction. But who is he really, and why has he come? As love blooms and the world stops spinning, the secrets of the girls’ past begin to unravel and escape is the only option.

A sumptuously written novel of love and grief; of sisterly affection and the ultimate sacrifice; of technological progress and climate catastrophe; of an enigmatic bear and a talking whale—The End of the World Is Bigger than Love is unlike anything you’ve read before.
