Six Days - Philip Webb [Used Book]

For Cass and Wilbur, the life of a Scav is all they have ever known ― ransacking what's left of London for a lost relic no-one, not even their new masters, has ever seen. But when two strangers from another time arrive, scavving will never be the same again. Buried beneath the rubble is something waiting to be found - with the power to transform the world. But, they have only six days to find it.
