A nailbiting story of survival'
-- GUARDIAN

May Knox floats in space, the only survivor of a catastrophic accident. There is just one person who can save her - and his life is in danger, back on Earth.

It's Christmas Day, 2067.

Silent Night drifts across the ruins of a wrecked spaceship, listing helplessly in the black. A sole woman, May, stirs within - the last person left alive of a disastrous first manned mission to Europa, a moon of Jupiter.

There is only one person who can help her - her ex-husband Stephen, a NASA scientist who was heading up the mission back on Earth. Until, that is, she broke his heart and he left both her and the mission.

As May fights for life, Stephen finds his own life is under threat, putting both of them at risk.

In this twisty, gasp-inducing thriller, when each breath is a fight for survival, their relationship is the difference between life and death.
