In the 34th Horrible Harry book, Mary's plans for a perfect birthday party go horribly wrong--can her friends save the day? Mary is always neat and organized, while Harry is horribly messy. But even Mary’s carefully planned schedule can’t help when things go wrong at her own birthday party. The party is supposed to start with the kids from Room 3B taking an exciting train ride, but when their train is delayed not one . . . not two . . . but three times, Mary’s plan is completely ruined! She thinks the only thing that can make her feel better is cup after cup of sugary Island Punch—even after her mom tells her to stop. But what Mary doesn’t know is that Harry has his own wacky ideas for saving Mary’s big day. Can the kids still have fun even when nothing’s going the way it’s supposed to, or will this be the most horrible birthday ever? Praise for the Horrible Harry series: "Room 2B is every child's dream...This is one school story which rates an A+."—School Library Journal (Horrible Harry and the Green Slime) "Another perfect chapter book for transitional readers."—School Library Journal (Horrible Harry and the Drop of Doom) "Kline has an exceptional talent for capturing the language, humor, and group dynamics of a primary grade classroom...

Another uproarious caper in the Horrible Harry series, and this time Harry's not the one breaking the rules! Everyone in Room 3B knows that if Miss Mackle sees you playing with toys at your desk, she'll confiscate them for her June Box. So when a substitute teacher catches good girl Song Lee with a pink origami pig, into the June Box it goes. The problem is that this origami was to be a birthday present for Song Lee's grandmother. So Song Lee does the unthinkable: she breaks into the June Box to free her pig. Now Harry, Doug, and the rest of the kids have to work together--before they all wind up in horrible trouble!

Horrible Harry says goodbye in the 30th anniversary finale of a beloved series! The last day of third grade is approaching fast, but a farewell to Room 3B isn't the only goodbye Doug has to say this year. Song Lee and Mary are busy preparing an end-of-year present for their favorite teacher, Mrs. Flaubert, but their excitement can't distract Doug from Harry's suspicious silence. When Harry finally admits that his family is moving to a whole other town, Doug can't believe his ears. How will he survive fourth grade without his best friend?! But Harry has a more pressing question: who's that moving in to the empty house across the street from him? And what could these new neighbors mean for their friendship?

Horrible Harry is at it again in his rollicking 36th story as he and his classmates participate in South School's Field Day! That means bean bag tosses, relay races, tug-of-war, and a mystery prize. Harry and Doug are determined to win, but at what cost? Original.

When his friend Doug is infested with head lice and Mary convinces everyone to stay away, Harry and his other friend Song Lee stand by Doug and declare war on the bugs in this 35th installment.

Song Lee is as nice as Harry is horrible! She may seem shy, but beneath her sweet smile is a brave, spunky girl with a great sense of humor.

Horrible Harry has caused a lot of trouble at school before, but he's never caused trouble like this. When Sid ruins an origami animal Song Lee made, Harry defends her by declaring triple revenge! No one knows when, where, or how, but Harry is going to get Sid back. Will it be on pajama day, when the kids wear their nightclothes to school? Will it happen in Room 3B? Or will Harry's ultimate revenge mean Sid is the only one not invited to Harry's ninth birthday party?
