Which book could you get lost in time again?

I originally intended to do something different for this blog, but as I went to save the blog the site crashed and everything was lost. 

Here I go.

Plot Twist

Now lets move on.

In my last blog I asked if you were a reader? I shared with you that I'm a reader as well. This time I'd like to ask if you have that one story that you could get lost in over and over? It may be the one that began your whole love of reading. Or it may be a story that you came across by chance and fell in love with it. 
For me it has to be J.R.R Tolkien's The Hobbit. Years ago I was given a box set of the Hobbit and the Lord of the Rings. I've read all of the books, but the one I come back to time and again is The Hobbit. I can't quite place my finger on exactly why I love that book. All I really know is that I do. Seeing the story line played out on the silver screen is a treat for me, but I think even after the movie sits on my shelf I will still crack open the pages of the novel and once again go on an adventure with Bilbo Baggins.
If you have a book that you can get lost in over and over let me know what it is. If you know why you love it then let me know that as well. I'm truly curious to hear what you truly love to read.
