What is love? With this original story collection, David Levithan proves that love is a many splendored thing, a varied, complicated, addictive, wonderful thing.
How They Met, and Other Stories is a book of short stories. This always has its pros and cons. When you love a certain story or specific characters, you never get them for more than twenty pages, which sucks. But if a story isn't for you, hey--maybe the next one will be! My friend read it shortly after I did and, though different stories were her favorites, we both enjoyed it immensely.
Every story in How They Met is about--you guessed it--how a couple met, but sometimes more about what happened after than the actual meeting. The types of relationships vary--two boys, two girls, a boy and a girl--one story even focuses on a boy and his mom. Some of the stories were so perfect I wanted to copy them and hang them in my room. This is a perfect, sweet little book. It would be a great gift to a boyfriend/girlfriend who is a reader since it's pretty romantic-y.
