The signal from below

Something eleven kilometres beneath the Pacific has been transmitting for four billion years. It has just started using your voice.

When marine physicist Dr Lena Vale extracts human speech from an impossible signal rising through the Earth's crust, she finds fourteen voices she recognises. One of them is her own, saying words she has not yet spoken.

The descent platform Thalassa carries eleven scientists past the floor of the Challenger Deep and into a shaft that should not exist. The deeper they go, the less the world behaves. Cameras record a crew member who died in 1962. A corridor appears in a bulkhead and vanishes before it can be measured. A man's broken leg begins to heal into something that is not bone, aligned nine degrees off vertical, pointing down.

Then they find the structure. Forty kilometres of it, grown rather than built, and inside it the drafts: every species that ever lived, filed in order, in columns of black bone.

The transmission is not a warning. It is a countdown. And when Lena finally understands what it is counting, she will understand why there are human beings on this planet at all — and that it was never an accident, and never for us.

Some things are not buried to keep them safe. Some things are buried because something needed somewhere to put them.

A claustrophobic, slow-burning novel of deep-sea terror and cosmic dread, for readers of The Luminous Dead, Blindsight and The Fisherman.
