*squees with you* Hooray! I haven't read that one, but Laurie Notaro is absolutely hilarious, and I think you'll like her. She, too, is often overly fond of puns. ;)

The Namesake is the most serious of all of these, but the prose is gorgeous and the characters are so real that what they do and what they go through just hurts, sometimes. And let me know when you finish Rant, because gaaaah, I want to have someone to dissect and discuss it with. It has time-traveling werewolves and a tooth museum and a horribly wonderful dystopian future! :)
