I would like to say Harry Potter, but I just used that for a challenge the other day. As off today I am making a slow progress with A Song of Ice and Fire, and so far this is one of the most quotable series I have read. My choice for a book I can quote is A Game of Thrones by G.R.R. Martin.
I’m half-way through the second book in the saga. These books are wonderful, and I really like to savor the moment by taking my time with them.
