I love to write, read, and live in books. I think that a book is like a life you have yet to discover, until you stare intently at the cover, and then finally decide, 'ok I'm ready'. You just fall deeply into another world of characters and plots. You fall in love with characters, you develop a true hatred for a character. 
But most of all, you let your heart break then put itself back together, without it actually happening. 
That's what books do, or at least what they should do.
