One evening in early autumn, ten people drive into a tunnel through the Cape mountains – and find themselves trapped.
As their limited supplies dwindle, what do they do? Where can they go? What will they find?
Tunnel burrows deep into the psychologies and coping strategies that connect and disconnect these protagonists in a dark, tense and compelling human drama.
An urgent new novel, told through many eyes; a journey – terrific and mystical – through despair, memory, and love.
