Greg Gaines, a pugdy, socially awkward, a-little-off-his-rocker, and always wanting to be invisible is forced by his mother to spend time with a girl with Leukemia Greg says in the beginning that he hadn't learned anything from Rachel's death, but I happen to disagree. What he learned is written right there on the very last page.
This is a very good book(if you ignore all the vulgar words and profanity). It is witty and conversational(which some people may not like unfortunately). It is not some book bent on giving you Gandhi like advice when someone in your life contracts Leukemia though. It's cute and I liked it.
