Nacy Drew And The Kachina's Curse

I'm reading Nancy Drew And The Kachina's Curse. So far it's about a detective named Nancy, and she's helping her friends Chuck and Heather. Thier problem is that a kachina doll's ghost is haunting thier house and making bad things happen. In the book, before she went to Arizona she recieved a letter it said don't go to Arizona. I bet she was worried that something bad was going to happen. I bet she felt rushed because she had to decide if she wanted to go and she was leaving the next day. GA
