Query: funny until the last three chapters, which will depress you.

i laughed the whole way through this book. uncontrollably. it's beautiful how he just rambles about what's going on in danny's head & his character descriptions are great. the last 3 chapters, though, depressed me so much i could barely talk the rest of the day. but it's very introspective and intelligent. i highly recommend it.
