Status Updates From The Graveyard Book

Genre: This book is going to be a science-fiction type of genre. For how far I've gotten, the story line is about a baby that escaped its crib and went outside to the town's Graveyard. At the same time, a mystery man named Jack is out to get the baby, and kill him. But, the baby gets taken by ghosts of the graveyard, because the mother died and asked them to take care of her baby. Very fictional and scientific.
