I love to re-read books I adored with the first reading. I find I can get into the characters more, notice something deeper, or see something from a different perspective with numerous readings. However, I had to fall in love with the book the first time, often it happens within the first few pages.

Yeah, I'm with Trinity here, I can love a book, but I won't read it again. I may look back to it for a reference if I mention it to others, but I get too bored with a book I've read before, because I may not remember it exactly, but I know what's going to happen once a memory is triggered and then I just go "Why am I reading this when I know what happens?" and then I stop.
