Hiram the Elf has had enough—not only has Union Square Park been cleaned up and made safe, but everyone who visits the Square is so infernally nice. So with the help of Knut the rat, he launches a sneaky campaign to return Union Square to the "bad old days." A little dog poop on the walkways, a little soap on the monkey bars, and suddenly the regulars of Union Square are at war with each other. But a boy named Jack and his reporter friend Will know that someone must be behind all the chaos. Will they discover the culprit before it’s too late for Union Square?

With a lovably silly cast of characters that any reader will recognize, Jan Carr’s debut novel is a brilliant combination of big laughs and sly satire. In no time you’ll be rooting for Jack and Will to save the day... or for Hiram to wreck it!
