Deep and Dark and Dangerous

I'm reading the book Deep and dark and Dangerous.  My teacher read this book to us in fourth grade and, I really liked it so I had to read it again.  Reading it now it sounds way different but it was a while ago so I think its good. The book is about a girl named Ali, she lived with her mom because her dad walked out on them. One day her anut came and was talking about the cabain that her mom and her anut us to go to as kids.  She wanted Ali to babysit her dauther Emma for the summer and her mom started acting really weird and didnt want her to go because of the lake.  Ali didnt under stand why until she found a picture of her anut and her mom with another girl the picture was riped and you couldnt see the girls face. The only thing you could see is the first letter of her name. I dont want to give away to much so you should get this book yourself.
