"Every catastrophe begins with a little problem that doesn't get fixed." So says Pauline Green, president of the United States, in Follett's nerve-racking drama of international tension.

A shrinking oasis in the Sahara Desert; a stolen US Army drone; an uninhabited Japanese island; and one country's secret stash of deadly chemical poisons: all these play roles in a relentlessly escalating crisis.

Struggling to prevent the outbreak of world war are a young woman intelligence officer; a spy working undercover with jihadists; a brilliant Chinese spymaster; and Pauline herself, beleaguered by a populist rival for the next president election.

Never is an extraordinary novel, full of heroines and villains, false prophets and elite warriors, jaded politicians and opportunistic revolutionaries. It brims with cautionary wisdom for our times, and delivers a visceral, heart-pounding read that transports readers to the brink of the unimaginable.
