Solve the riddles, save creation.

For Vikki death is only a contract away, that is until she wakes up in a strange, remote village on the edge of creation. There she meets a ghostly monk who looks after the small church and an elderly librarian and his son who appear to be the only inhabitants.
That is until Matty and Emily arrive.
Young, vivacious, these young women seem so full of life, except that Matty died in an explosion and Emily was trapped in an underground cathedral with food and water running out.
So what brought them together? What binds them to this place?
In attempting to answer these questions, they discover that creation has contracted a virus and they have been summoned by the mysterious Veil to hack into the core and eradicate the problem. Can they do this before the virus sweeps through the whole of creation and consumes it.
