Greg Gaines is clueless. And since this book is a kind of journal from Greg's point of view, as a reader you see that sometimes Greg understand how clueless he is (ie: girls) and sometimes Greg is utterly clueless as to his cluelessness (ie: friendships). But he's both charming and annoying, and you root for Greg to come around eventually - because really, aren't we all clueless?
Greg's been carefully cultivating a non-persona all through high school. He's pretty happy that now, as a senior, he's not associated with any group, scorned by any clique, or shackled by any categorizations.
Then, his mother strong-arms him into a friendship with Rachel.
It's a funny book about friendship and growing up, about finding something only when you lose it. Greg's sure - right up until the last page - that he didn't learn a thing from his experiences, and he can't believe you're even interested. This light-hearted style makes the novel a quick read despite its thematic weight.
