Pedro is vast, but he is also hidden and mysterious, tucked behind locked doors and a colloquy of priests and doctors. A eucalyptus farm worker, he and several of his fellows fall suddenly ill from a strange fungal disease. None of the others survive, but Pedro slips into a coma and then, miraculously, awakes. His survival brings the attention of a foreign mycologist and an enterprising priest who reckons him a prophet, while his children are left to fend for themselves. Pedro, meanwhile, continues to lurk and rant, his words making little sense, his body succumbing to decay. His story haunts the lives of everyone else trying to survive amid the ruins, waiting—expecting—something to change.
