I really enjoyed the clever format of this book by David Levithan. Each entry is a word and the scene that follows relates the word to the relationship. At first, it seems disorganized since it isn't sequential in terms of time; it's in alphabetical order. But after the first few pages, it begins to solidify.
There are two threads that run through the entries which create the plot that makes this a novel rather then a list of words and random anecdotes. These two threads are alcoholism and infidelity, which lend some seriousness to an otherwise lighthearted picture of a couple falling in love.
It's a quick read and makes for a good gift for a lover. (At least, I think so. You'd have to ask my boyfriend if he agrees.)
