Blacker

A mysterious black sphere has appeared in the north of Scotland, absorbing energy and light as its influence spreads. Soon, the whole world will be plunged into a forever night nothing can survive. John MacGregor reluctantly enters the sphere, his blindness giving him a unique talent for negotiating the dark interior. Military psychologist Eilidh Hunter becomes MacGregor's level-headed ally, guiding the veteran through the horrors that lie within - and beyond - the sphere's deadly influence.
