Night of the Giant Everything (Goosebumps: Hall Of Horrors #2)
Steven is a big fan of magic. The problem is that most of his tricks come at the expense of his friends Ava and Courtney. The girls decide to get their revenge on Steven by tricking him into drinking a strange mixture of chemicals. Steven starts to feel weird. Either his toothbrush is growing or he is shrinking! The world feels like a much bigger place when you're only nine inches tall. Will Steven be able to make it through his gigantic house to find help? And even if he does, will he ever be back to his normal size again?
