Quantum

'In a time when everyone sees a flat world with the sun moving around us, one man watches the sun's arc through the sky; he looks at the shadows cast about him and he sees the world is round; he sees us moving round the sun. Søren is that man in our time.'
Haunted by blood, Søren plays his Comms-implant recording of yesterday to once again witness the horror as a colleague commits suicide. A young and gifted researcher, Søren is on the brink of making a major scientific advancement. Combining the Quantum principle [that atoms can exist in two places at once / of Entanglement where two particles can effect each other over vast distances] with advances in 3D-printing technology, he is effectively about to make a revolutionary translocation device.
Also running parallel to the main story is a book which Søren is reading called The Cave. The mysterious titular cave results in anyone who enters simply vanishing without trace. The book soon causes Søren alarm as he realises his own research can be thought of as the metaphorical cave where some things are best left alone. However soon he has gone too far and the corporation he works for won't let him stop his research without endangering those he holds close.
