Every day on her spy route she "observes" and notes down anything of interest to her:I BET THAT LADY WITH THE CROSS-EYE LOOKS IN THE MIRROR AND JUST FEELS TERRIBLE.PINKY WHITEHEAD WILL NEVER CHANGE. DOES HIS MOTHER HATE HIM? IF I HAD HIM I'D HATE HIM.IF MARION HAWTHORNE DOESN'T WATCH OUT SHE'S GOING TO GROW UP INTO A LADY HITLER.But when Harriet's notebook is found by her schoolmates, their anger and retaliation and Harriet's unexpected responses explode in a hilarious way.

    With enthusiastic endorsements from bestselling luminaries as Lemony Snicket, Judith Viorst, Andrea Beaty, and many others, this entirely unique collection offers a surprise around every corner: from the ongoing rivalry between the author and illustrator, to the mysteriously misnumbered pages that can only be deciphered by a certain code-cracking poem, to the rhyming fact-checker in the footnotes who points out when "poetic license" gets out of hand. Adding to the fun: Lane Smith, bestselling creator of beloved hits like It's a Book and The Stinky Cheese Man and Other Fairly Stupid Tales, has spectacularly illustrated this extraordinary collection with nearly one hundred pieces of appropriately absurd art. It's a mischievous match made in heaven!
