Query: This was the best ghost story I've ever read!

Anyone who likes ghost stories would LOVE this book! I swear, it's the best book I've read in a long time! I usually take 2 weeks to read a book, but I got this one done in 4 days! I couldn't put it down! Everything in the book seemed so realistic, and had a spooky feeling throughout the whole book. I would recommend it to anyone who loves supernatural or ghost stories!
