Introduction: Dear Mom,Please don鈥檛 worry. I expected this. You will be at home around 2:15 this afternoon, during the school assembly, when you鈥檒l receive a phone call from a panicked administrator, stating that I and approximately 85% of my schoolmates have vanished, along with a few people from the surrounding schools.It鈥檚 okay, we鈥檙e fine. Do you remember that story I told you a couple weeks ago, that I saw in a dream? It鈥檚 just like that. We鈥檒l be fine. We won鈥檛 be able to return, but I promise you鈥檒l see us again.You probably won鈥檛 believe me, but you have 17 days until you can join us. In that time, you need to pack anything you think is important. No, you can鈥檛 pack the entire house. Size limit is anything you are touching that night at midnight. No, that doesn鈥檛 include your chair. Yes, it does include the cat carrier. Good luck convincing Dad to help you pack.Everyone who worries about our disappearance will receive a dream in about three days (at midnight, so make sure you鈥檙e asleep), so ensure you make contact with the others and convince them to at least give it a shot. Whether they believe or not doesn鈥檛 matter as much as the intention to join us.Please, don鈥檛 be scared. We鈥檙e fine. Just get ready.Love, Your (missing) daughter,     Tabby...
