Diary of a Wimpy Kid: Partypooper

It’s Greg’s birthday―and you’re invited to the chaos. In Partypooper, the 20th book in Jeff Kinney’s global smash-hit Diary of a Wimpy Kid series, Greg Heffley is planning the ultimate party―for himself.

But when the guest list grows, the decorations flop, and the surprises backfire, this birthday bash turns into a total blowout―just not the kind Greg had in mind.

Packed with cake disasters, family fiascos, and classic Wimpy Kid humor, this book is perfect for readers ages 8–12.
