The Lover's Dictionary by David Levithan

David Levithan has a way with words. I have felt that with every book of his I've read (which is really only 5, including this one, but still, it's the reason I fell in love with his books). He's amazing and brilliant and wonderful.
The Lover's Dictionary is a very brief book (I read it on my lunch hour & one 15 minute break) in which Levithan defines words that tell the story of a relationship. The entries are brief thoughts on a moment or relate an entire episode in their relationship. There's a quiet beauty to the entries, even the angry ones (which is interesting to see the anger pop out between different words, so you don't get the whole story at once), and Levithan brings you into this relationship and the mind of the narrator, and I found it very easy as a reader to identify with many of his entries.
I like how he had part of a conversation in one entry, then further on went back to that conversation, and included just a little more, enough to illustrate the word, teasing the reader to keep reading to find out the whole story. Like with all books that capture just moments of a character's life, The Lover's Dictionary has beautiful moments that build an image in your mind. The great thing about Levithan is that he does it with so few words. One of my favorites:

whet, v.
You kiss me when you get home, and when I kiss you back longer, harder, you say, "Later, dear. Later."

I simply love the image this creates in my mind with so few words. It's difficult to give a full description of the story of this book, but if you're patient, interested in words and imagery, pick up the book. It will not take very long to finish (or to suss out if you like it or not).
