SPOILER ALERT!
Welcome to Dead House (Goosebumps, No. 1)

This is a child book no doubt about it. But it was horror nevertheless...
A spill from a factory killed all the habitants from Dark Falls. Afterward they were resurrected and they need fresh blood every year, like undead vampires. To that they lure some people every year to a house, that they call Dead House, and kill it's occupants (as they became new undead). The ending leaves us with a question (as other books from Goosebumps. They destroy Mr Dawes but as they are leaving the city they saw Mr Dawes showing the house to new peoplle.
Excelent. This is one of those series alongside "Uma Aventura" that my unborn child will read... if he wants it.
