Where the World Ends is a 2017 young adult novel by British writer Geraldine McCaughrean and illustrated by Jane Milloy.

[5] Reviewing the book, Booklist's Maggie Reagan wrote, "McCaughrean ... slips into the cracks of the human soul, dissecting with compassion the many paths that a person might take when confronted with such a challenge.

The design of the book is as austere as its subject ... and, in an afterword, McCaughrean describes the tragic true story that inspired her own.

[4] Writing for Shelf Awareness, Emilie Coulter highlighted how Where the World Ends "stuns with its dark narrative and haunting visual imagery."

She further commended McCaughrean's decision to include "illuminating back matter, like a glossary, and an illustrated list of the birds of 18th-century St. Kilda," which helps readers to "[explore] what happens when the everyday-ordinary turns disastrously extraordinary.
