Books in Horrible Harriet series

It’s a horrible day for Harry: a classmate is calling him names; his library book is overdue; he’s last in line for a turn to be the Room 3B VIP. Worst of all, it’s cold and icy outside again, which means no outdoor recess. It’s all too much for Harry—he starts to go cuckoo! Fortunately, there is a solution to Harry’s problems . . . but it comes from a very unexpected source.

Horrible Harry has discovered the biggest mystery ever in Room 3B! There's a locked closet in the classroom that's been sealed off for years, and he wants to find out what's inside. Harry can't solve this mystery alone, so Miss Mackle, Song Lee, and the rest of the class join in the detective work. Along the way they encounter some surprises--from old school rumors to a hidden trap door to . . . eyeballs! What secret treasures does the closet hold? Is it something more horrible than even Harry can imagine?

When Harry finds an ad in the paper for a used telescope, Miss Mackle suggests that the class raise money to buy it. The telescope will make their moon study unit even more exciting! Once they get the telescope, the class can have a nighttime moonwatch. But Harry wants to do more than watch the moon-he wants to go there! Can Harry really take a trip into outer space? "There's laughs aplenty in the short snappy text-just the thing to turn new readers on to books." ("Booklist")

Doug can’t believe what Harry has done, but Harry thinks his risky move is worth it. After all, he cracks the case and tells everyone who Miss Mackle is going to marry . . . but does Harry have his facts straight? Or has he made a horrible mistake?
