Diario de Greg (Used Hardcover) - Jeff Kinney
Kinney does a masterful job of making the mundane life of boys on the brink of adolescence hilarious. Greg is a conflicted he wants to do the right thing, but the constant quest for status and girls seems to undermine his every effort. His attempts to prove his worthiness in the popularity race (he estimates he's currently ranked 52nd or 53rd) are constantly foiled by well-meaning parents, a younger and older brother, and nerdy friends. While Greg is not the most principled protagonist, it is his very obliviousness to his faults that makes him such an appealing hero.
