THREE WORDS IN MANDARIN.

THAT’S ALL IT TAKES TO END THE WORLD.

Planes circle, unable to land. The phone lines are down. The power is out.

And the only person who knows why is dead.

That man was Sebastian, a handsome politician on the rise. Charlie, his political attack dog and childhood friend, just watched him kill himself.

Then the Secret Intelligence Service comes knocking.

What the hell did Sebastian do?

And can Charlie find out before the world implodes?

The Peak is a nailbiting and fast-moving international thriller that weaves a story of friendship and betrayal together with the ruthless geopolitics of China's rise, set in the last twenty four hours of the world as we know it.
