I met one of my best friends--whom I later married much to my delight--over books. Early in our friendship, I asked what to offer as a gift for birthday and Christmas. The answer: "Books. Send me a box of used books, a collection of the best ones you've read."
I remember going to my favorite used bookstore to shop that November. I took a little hand-written list, titles I had on hand in my home library, but when I began browsing the bookstore shelves, I was astonished at how many books I knew--and loved.
I think I bought 30 books that day. Everything from children's books (The Dark Is Rising series) to young adult to adult fiction. Fiction was the only requirement--something to get completely lost in.
